SpMp is a YouTube Music client with a focus on language and metadata customisation. 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. Key features: Metadata Edit song, artist, and playlist titles Set separate languages for app UI and metadata like song titles QOL Pin any song, playlist, album, or artist to the top of the main page Download songs for offline playback Select multiple songs/artists/playlists from any screen to perform general or context-specific actions (ex. shuffle just part of the queue) When adding a song to the queue from the long press menu, a specific position can be selected and songs are placed in the order you add them by default Connectivity In-app YouTube Music login for feed personalisation and interaction Customisable Discord rich presence (with image support) Lyrics Display lyrics from PetitLyrics, with timed lyrics support Timed lyrics are displayed in a toggleable bar above every UI page in the app Show furigana for Japanese kanji within lyrics using Kuromoji And more (see the wiki for a full more complete list of features)
