I was all set to just keep pushing through the bugs on AM, because I was really liking the suggestions and the nice attempt at iTunes integration. Then suddenly a bunch of my albums started giving me a "looks like this isn't available anymore" message when trying to play them on my phone or iPad.
I'll keep my eye on the future of AM, but for now, I've re-subscribed to Google Play All Access. I really do love it, but Apple Music's suggestions and For You section really are much better than anything Google has on board.
