I’ve been using Pi Music Player, and I’d like to switch to something free and open source. The only feature I absolutely need is the ability to import m3u8 playlists from the file system into the app’s own playlist database, in bulk. That is, it must be able to import /Playlists (or any folder that contains playlists) that point to local music on my phone, overwriting playlists of the same name it previously imported. This is how I keep my phone’s playlists in sync with my PC’s. Pi Music Player supports this. It also supports creating playlists on the phone and exporting them to a file, but that’s less important to me.
