Hate it. I loved Play Music. That was perfect. 1) I prefer to buy songs and albums, so I can own the mp3 files, rather than pay for streaming. 2) I tried to spread my purchases between Amazon, iTunes, and Google. YT Music has no "buy" ability. 3) YT Music's focus features are obviously created to drive people to the paid subs. Believe it or not, I rarely want to watch music videos. When I do, regular YouTube has been just fine for that. I like to listen to music while I read/browse.
