Got this game today (release date) and have made short work of it and completed it on easy mode already.
The tracklist (in my opinion) is waaay better than the first game, but the easy mode is far too easy.
Also, I don't think there is enough songs on it, wish they could put more on or allow the capability to download tracks like you can on the PS3 version.
Still its good fun to play, and I still have to work my way through the harder levels.
