I started off loving it. I fell hard for the For You section. It was a very slick mix of stuff I obviously love, classics that I don't frequently listen to but love all the same, and new stuff just outside of my direct familiarity. It's done very well and it's very obvious that these playlists are put together by humans who have a pretty good knowledge of the genre they are working with.
One side note is I have ZERO use for the music played on Beats 1. I've tuned in many, many times only to hear music I'd never feel the desire to listen to in a million years. I won't count that against them, as it's obviously not geared toward a middle aged indie/punk rock listener.
After a month of bliss, the weirdness set in.
Random stopping of the music.
Downloaded music was showing lots of doubles, triples, or even more of one song. Tried multiple ways to correct it, clearing all downloads and redownloading but nothing would correct it.
Then there was the Unable to Download error.
There is the showing only offline music not working correctly.
The issues with offline music have rendered AM unusable for me.
For now I've disabled AM and put the Music app in my Crapple folder.
The upside is Apple Music's shortcomings have driven me to check out Google Music again, which is pretty fantastic and has lots of albums that AM (and Spotify) are missing, namely the Dead Kennedys, 7 Seconds, Youth Brigade (and any BYO Records stuff).
I do really miss the For You section but I'll make do for now. If Apple Music is fixed before my 3 month trial is up I'll seriously consider keeping my subscription active. If it's still a mess it looks as if Google will be getting my loot.
