Yeah, I'm in the same boat. Only thing it does is suggest albums based on my listening habits or if it's new releases by artists in my library.
I am also a subscriber. It's just always been there in my library. tons of crap from kanye, john mayer, xzibit etc.. I think I've finally got most of it cleared out. It's taken me two hours to delete everything they added via the web interface.
Have you perhaps logged in with a Nexus device? I know that my Nexus 7 (2012) came with quite a bit of free media to promote the recent redo of Google Music, Google Play TV/Movies, etc.
yes. maybe that's it. I've had a galaxy nexus, a nexus 5, and two nexus 7s.
Wow, that's really weird to hear. Google's never done that to me.
