I used to go semi-frequently. I have specific musical tastes. Now, I can't help but get it to shuffle to something like 9/10 songs that I would never want to hear.
Limiting to a genre, in the old version, it used to be 1 or 2/10 that I didn't care for. I've tried a few times, but effectively have stopped using it. I can't find the same feature. The "moods" thing is not nearly as effective. It feels like it's become a radio station, and I don't listen to it for the same reason: I have no control over what it plays, and it seems to play "pop" (don't read that literally, just "things lots of people listen to") music all the time, and never what I want to hear.
I also, generally, find the new interface very difficult to use. Lots of mystery meat navigation and hard work to find what I'm looking for.
