The main reason I won't use Google Music is the lack of playlist folders. There's no way to organize playlists, and the player becomes quite unusable if you have even a few dozen playlists.
I'm surely not the only one who likes making and sharing playlists for different moods and occasions. It would be interesting to know why such a simple yet important feature is missing.
Google doesn't really do folders (see gmail), but playlist tagging would certainly be a feature I'd appreciate.
I personally am finding they are going backward though, I've been a subscriber for a while but they've just removed the radio icon over radio stations so it's hard to see in the recent activity whether it was a radio or actual album.
