Rock Revolution is probably better than this. One of the most shocking things was that they make you unlock songs. The only songs at the start are twinkle twinkle little star and other songs like that. No access to Nintendo songs until you unlock them.
The control area actually more complicated than Rock Band, either Drums or Guitar. Unlike those games where it makes sense, here you can either produce noises just by shaking the remote (or pressing a button for violin or flute), but if you want to play slightly less shitty notes you're required to hold down some combo of analog stick directions and buttons then shake. It's not intuitive, you don't feel like you're playing a real instrument, you just feel dumb and the initial sad humor when playing with friends became just sad and depressing. At least with others around there is a sense of wahjah that you all are gigantic assholes, but you're assholes together. It's a bit like being a PoW where a bond forms between the crew. I was the John McCain for borrowing it to try the solo drum parts.
