I'd buy this in a heartbeat if I could. No big hopes that it will come soon where I live though - google is just not hungry like Netflix and co it seems.
But no list view for music. Because when I'm on a tiny mobile screen I want to see over 3/4 of my artist list covered in album thumbnails that I don't recognize and half the text cut off because grid view is the hot new thing.
Still, hard to beat the value and the mood-based radio stations are awesome.
