SpMp has been succeeded by Kanon

SpMp was my first large-scale Android/Compose project, and after over two years of development it became very difficult to maintain. Kanon is a rewrite-turned-successor of SpMp, and shares the same basic features and core design.

While SpMp remains available on this repository, it is no longer maintained, and has not been since late 2024. If you use SpMp, please be aware that you may encounter bugs or broken features, and that these will not be fixed.

About the project

I started this project after I got tired of dealing with YouTube's official music app's lack of language features and customisation. I tried several alternatives, but all had at least a few issues that bugged me.

So instead of spending a few weeks learning the codebase of an existing project and contributing to it, I decided to spend almost a year (as of writing) creating my own solution.

Contributing

Pull requests, bug reports, and feature suggestions are welcome! This is my first Compose project (and also the largest project I've ever done in general) so there's probably plenty of room for improvement.

The app is currently being developed for both English and Japanese. Contributions for other languages would be greatly appreciated! Information about app localisation can be found here.
