Fediverse, I am once again calling upon your techie powers! 💾 :server: :pentagram:
I'm looking for a mobile app (preferably for both Android and iOS) that allows me to create music playlists and download them for offline listening from a (FRITZ!)NAS full of MP3s, e. g. for car rides.
Doesn't have to be free, just no subscription model, please. All apps I've found so far can stream, but not download. Is there something out there I may have missed?
