This looks promising, very similar to Metro but an active project. Thanks for sharing.

If you need it for Android, I tried quite a few. I had the same requisites, offline, lyrics for flac files, I ended up using Metro: https://f-droid.org/packages/io.github.muntashirakon.Music/

Very minimalist and do the job very well. I use the field “Composer” to sort my lists.

The way that I see, Linux phones will only get traction when we are able to install android apps and use high end spec phones with good security. I hope that I’m wrong.
