I am in the process of moving away from Spotify by downloading my music offline. The files vary in types (.webm, .m4a, etc.), and I would like a way to sort them into playlists on Android. What are your suggestions?
Musicolet, lets you create playlists but it can also create randomized playlists and have multiple queues at the same time. It's not FOSS though, if that's something you care about. But it doesn't even connect to the internet so I don't mind.
