This is great fun, especially when playing on multi player. There are alot of stupid instruments such as rapper, DJ and even cat and dog which are just a good laugh, can't finish the song because your laughing the whole way through.
I think this is the only game my entire family actually enjoys and can play together because controls are so easy - you can pretty much just shake the Wii remote and your playing the instrument.
As I said, it's nothing like playing an actual instrument because the movements are pretty vague, just moving it about will get it to make a sound. You don't even control what note you play so that makes the whole thing much easier even if it is unrealistic.
A great feature of the game is being able to save and re-watch videos. This brings hours of fun itself and being able to design your own CD cover just adds to the enjoyability of the game.
The Wii balance board feature in this game isn't great, it's quite hard even for someone musical like me but good if your up for a challenge. (And have the balance board, of course.)
I like this game and would recommend if you want to get more members of the family enjoying the Wii as it's quite easy. Great game!
