Features

• Native TUI: Integrated Rust TUI (powered by skim) for deep UI customization and instant fuzzy searching.
• Lightning-Fast Indexing: Automatically scans your music directories utilizing multi-threading, caching metadata (Artist, Album, Title, Genre) into a JSONL index.
• Self-Healing Index: Automatically validates index integrity on startup. It detects corruption (e.g., from power loss), surgically repairs broken lines to save your library, or triggers a smart rebuild to prevent crashes. In a blink of an eye.

• Rich Metadata Previews: View song title, artist, album, and genre directly in the skim preview window.
• Interactive Selection with Multiple Modes:
  • Directory Mode: Navigate folders with clean names instead of full paths.
  • Track Mode: Fuzzy-search individual tracks with metadata previews.
  • Playlist Mode: Find and play your saved .m3u or .pls playlists.
  • Tag Filter Mode: Drill down by genre, artist, album, or title interactively.
  • Play All: Instantly play your entire indexed library.
  • Search & Stream URL: Search YouTube or stream URLs directly from the menu.
  • Radio Mode: Built-in support for diverse internet radio stations. Stations are sourced from respected, ad-free streams (discovered via the open Radio-Browser.info database, aside from the official LISTEN.moe), including:
    • LISTEN.moe (J-Pop / K-Pop) - Includes live WebSocket metadata synchronization (listen.moe).
    • SomaFM (Ambient / Metal) - Listener-supported, commercial-free radio from San Francisco (somafm.com).
    • Lofi 24/7 (Lofi Hip Hop) - Provided via fastcast4u.
    • Vocaloid Radio (Vocaloid) - Independent SHOUTcast community stream (vocaloidradio.com).

[!NOTE] Please consider donating directly to these independent stations through their websites to help keep their servers running!

• Settings: Manage mpv-music settings directly from the menu.
• Direct File/URL Playback: Instantly play local audio/video files or URLs (YouTube, streams) without going through the menu.
• Custom Directory Support: Pass a folder path to browse and filter only that directory instead of your full library.
• CLI Filtering: Use flags like --genre, --artist, --album, --title for direct filtering. Pass a value or omit it to open an interactive picker.
• Smart Matching: CLI filters attempt exact matches first, then fall back to partial matches with disambiguation.
• Configurable File Types: Support for both audio and video extensions, easily tweakable.
• Custom MPV Flags: Pass mpv flags directly or set defaults in the config.
• Video Toggle: --video-ok lets you include videos in your library scans.
• Visual Playback: --watch (-w) forces the MPV window to open, allowing you to watch videos or see cover art/visualizations during playback.
• YouTube Auto-Config: Automatically detects JS runtimes (Deno, Node, QuickJS, Bun) for yt-dlp YouTube playback.
• Clean Logging: Verbose (-v) and debug (-d) modes, multi-session logging (logs/session_<timestamp>_<pid>.log) with configurable retention, and built-in interactive log viewer (--log).

Dependencies

Required:

• mpv - https://mpv.io
  • Compatible forks (such as mpv.net) and custom binary paths can also be used. You can configure this via the player option in config.toml.

Optional (but recommended):

• yt-dlp - for playing URLs. https://github.com/yt-dlp/yt-dlp
  • Compatible forks and custom binary paths can also be used. You can configure this via the ytdlp option in config.toml.
• JS Runtime - for YouTube playback (Deno, Node.js, QuickJS, or Bun). Deno is recommended.

[!NOTE] YouTube playback now requires a JS runtime to bypass anti-bot protections. mpv-music automatically detects and configures Deno, Node, QuickJS, or Bun for yt-dlp.

If you installed yt-dlp via a package manager (apt/dnf/pacman) instead of the official GitHub binary, it might be missing components. Try enabling the remote fix in your config (mpv-music --config): ytdlp_ejs_remote_github = true

Installation

Supported Systems

• Linux: Native. The app is built and tested primarily for Linux.
• WSL (Windows Subsystem for Linux): Fully Supported.
• macOS / BSD: Should work fine on macOS and BSD systems. Check FAQ.
• Windows (Native/Git Bash): Fully Supported. Check FAQ.

Fedora (Copr)

If you are on Fedora (supports active Fedora releases on x86_64 and aarch64):

sudo dnf copr enable furqanhun/mpv-music
sudo dnf install mpv-music

(See the furqanhun/mpv-music Copr page for repository details).

From crates.io (Recommended)

If you have Rust installed:

# Full installation with update checker
cargo install mpv-music --features update

# Minimal installation (smaller binary, no --update flag)
cargo install mpv-music

Pre-built Binaries (Recommended)

[!TIP] Unsure which binary is right for your system? Visit the interactive Downloads Page to download the exact version compiled for your OS and architecture.

1. Download the latest binary for your architecture from the Releases page.
2. Make it executable and move it to your path:

   chmod +x mpv-music
   mv mpv-music ~/.local/bin/
   

or Alternatively, you can use the automated installer scripts to handle the process:

Linux / macOS:

curl -sL https://raw.githubusercontent.com/FurqanHun/mpv-music/master/install.sh | bash

Windows (PowerShell):

iwr https://raw.githubusercontent.com/FurqanHun/mpv-music/master/install.ps1 -UseBasicParsing | iex

From Source

Requires Rust 1.93.0+.

git clone https://github.com/FurqanHun/mpv-music.git
cd mpv-music
cargo build --release
# Binary will be at target/release/mpv-music

First run (setup):

mpv-music

[!IMPORTANT] Running mpv-music for the first time will automatically index $HOME/Music. It is recommended that you first run mpv-music --manage-dirs to customize music directories before indexing (unless you only keep your music in $HOME/Music). And if your music is on an HDD, you may want to run --serial or set serial_mode = true in your config, using mpv-music --config.

That creates:

• Config: ~/.config/mpv-music/config.toml

• Index: ~/.local/share/mpv-music/music_index.jsonl

• Logs: ~/.local/share/mpv-music/logs/ (e.g. session_<timestamp>_<pid>.log)

The project respects XDG standards and uses the directories crate to automatically support proper config/data paths across Linux, Windows, and macOS.

[!TIP] Optional: Clean Terminal Icons (Nerd Fonts) By default, mpv-music uses standard emojis that work everywhere out of the box. If you prefer crisp monochrome icons that automatically follow your terminal's color theme, set nerd_fonts in config.toml:

# Options: "none" (default), "mono", "normal"
nerd_fonts = "mono"

• Font Recommendation: You don't need to replace your system font. Simply download Symbols Nerd Font (SymbolsNerdFontMono-Regular.ttf for "mono", or SymbolsNerdFont-Regular.ttf for "normal") as a fallback font.

Indexing

Your music library is indexed to:

• Wherever your system defines program data should go; on modern Linux systems, this defaults to ~/.local/share/mpv-music/music_index.jsonl

Why?

Searching the filesystem with find every time is slow, especially if you have a large music collection. So mpv-music caches an index using JSONL (JSON Lines) for:

• Fast filtering
• Instant append updates
• Metadata previews
• Offline-friendly behavior

Maintaining:

• --reindex - Full rebuild
• --refresh-index or -r - Smart update (only processes new/modified files)

[!TIP] Indexing vs. Watching:

• Use --video-ok (or set video_ok = true) to scan and include video files in your library.
• Use --watch (or set watch = true) when playing to actually show the video window.

Example: mpv-music --video-ok --reindex to scan, then mpv-music -w to watch.

FAQ

Q. Why Rust?

The Bash version was a hack that grew too big. It was parsing hell, ngl. That being said, the reason for Rust is simple: I first thought about Zig, C, or Rust, but having read a couple of Rust chapters few months or years ago, reading Rust code felt way more natural. Plus, with the compiler keeping things in check, I could make sure LLM suggestions wouldn't fuh me up in places I wasn't even aware of.

Q. Why not use a "real" database like SQLite?

Because you don't need it. Your music library is likely under 100,000 tracks. A flat JSONL (JSON Lines) file is:

1. Human readable: You can cat or grep it.
2. Fast enough: We load and parse 20,000 lines in milliseconds.
3. Corruption proof: If one line gets corrupted, you only lose one song, not the whole database. And it is easily detectable—plus with refresh-index, it's automatically fixed.

Q. How well supported are Windows, macOS, and BSD?

• Windows: Well, despite me testing it a bit on a vm on ma potato laptop, I cannot guarantee no bugs on it, as I test it like I am touching acid. I didn't test it extensively, more than launching mpv correctly and reading just one song/updating and spawning the mpv, and radio mode. It's no longer in beta, but in my head it will always be, let's say that. Windows is still Windows.
• macOS / BSD: It compiles and follows Unix standards, XDG paths, and standard CLI conventions, so it should work fine on macOS and BSD systems. But since I don't daily-drive a Mac or BSD machine, I haven't tested it extensively either.

I really need someone to test it on Windows (and Mac/BSD) tho, fr. Any feedback or bug reports are super appreciated!

Q. YouTube playback isn't working!

That is likely not a bug in mpv-music. YouTube is constantly fighting yt-dlp.

1. Update yt-dlp (yt-dlp -U).
2. Make sure you have a JS runtime (Node, Deno, Bun) installed. YouTube now requires executing JavaScript to decipher video signatures. mpv-music tries to auto-detect this, but it can't perform miracles.
3. If you installed yt-dlp via package managers (apt, dnf, pacman) instead of official GitHub binaries, consider enabling ytdlp_ejs_remote_github = true in config.toml.
4. Or you can try changing the ytdlp_useragent in config.

Q. mpv-music isn't picking up metadata for video files or some other audio formats?

The original mpv-music utilized ffprobe to parse metadata from everything. The Rust version uses lofty (native Rust library) for metadata parsing, which is infinitely faster (in some sense) but supports fewer formats (mostly Audio). However, they should be enough for 99% of people.

Currently supported formats by lofty:

File Format	Metadata Format(s)
AAC (ADTS)	ID3v2, ID3v1
Ape	APE, ID3v2*, ID3v1
AIFF	ID3v2, Text Chunks
FLAC	Vorbis Comments, ID3v2*
MP3	ID3v2, ID3v1, APE
MP4	iTunes-style ilst
MPC	APE, ID3v2*, ID3v1*
Opus	Vorbis Comments
Ogg Vorbis	Vorbis Comments
Speex	Vorbis Comments
WAV	ID3v2, RIFF INFO
WavPack	APE, ID3v1

For unsupported formats, the indexer falls back to filename parsing. I may implement an opt-in ffprobe fallback in the future if there is demand, but right now there's me and one other person I know of that actually uses this and we don't need it. Actually, there are now an estimated 30–50+ users, but no one has complained so far since the vast majority just use Opus, FLAC, WAV, or MP3 these days.
