The hilarious thing is their Wikipedia scraping. Every time I select an artist I'm treated to some lame-style photo, and half the screen gets to tell me "Nirvana was a grunge band from Aberdeen with Kurt.....". Gee thanks Google, that was worth complicating the UI.
Playlist management is also worse than Windows Media Player. Like, how do you get that wrong?
This deal is sweet and I'd buy today, but Google is psycho when it comes to regions. Since it randomly thinks I'm in France or Hungary when in Denver, plus I travel between Canada and Guatemala, my guess is that features will randomly stop working or switch language. Otherwise, cool.
