Apple Music on cellular data is disappointing so far. It's quite noticeably low bitrate - and you don't need high-end headphones to hear the difference. Compared a few tracks side-by-side in Spotify & Apple Music in my car with non-audiophile equipment and it's pretty obvious.
This is really strange, because streaming music from iTunes Match on cellular sounds every bit as good as Spotify's 320kbps stream. It's just "Apple Music" tracks that are streamed at low bitrates.
This isn't a huge deal for me since I do most music discovery on wifi and then make stuff I like available offline, but I still really hope Apple at least adds the option to stream at a higher bitrate in Apple Music, like every other service.
Here's some good info on this:
