fyi nobody is complaining about this on the youtubemusic reddit which is the one of the first places I think we would hear about it if this issue was widespread BUT maybe its regional and hasn't hit the usa users yet.
The death of Google Music is long awaited and feared. Once it does die it'll be like the death of Google Reader 2.0. People are just getting twitchy with any little mistake Google makes.
Honestly, I'll be pretty bummed if they increase the prices. I stopped using youtube music / google play music awhile back as they ruined the experience for me there but have kept it for the ad free youtube.
There is also a googleplaymusic reddit which seems to be a more obvious place for google play music users.
