Switch to Apple Music. It has all the music Spotify has, the music is higher quality (all the way up to the highest quality you can get), exclusive radio shows you can’t get on Spotify, handmade playlists that are curated by a real human, a completely separate classical music site included at no extra charge, and more all for $10 bucks a month.
So Apple uses ALAC, which is it’s own version. Do you mean how much data is used when streaming? If so, I’m not sure. If you mean what’s available it’s:
High Quality (AAC 256 Kbps)
Lossless (ALAC up to 24-bit/48 kHz)
Hi-Res (ALAC up to 24-bit/192 kHz)
Nah, YouTube music.
Shit software (like utter garbage), iffy catalog, generally trash experience, but it fucking includes YouTube premium which is just incredible especially if you use vr.
Also they’re doing something weird where sometimes you can play video Playlists on audio only players like smart speakers. And you can always upload shit.
