Summary: It has a couple of decent songs to play , but most of them are not that great in general. It's annoying overall. A song that might be fun/decent/okay to sing will suck for the drummer, bassist, guitarist. If it's fun for the drummer it's boring for the rest. Same goes for the others.
Summary: Wanted to import songs into Lego Rock Band for my kids or into Rock Band 3 for myself. Was unable to do either. Apparently you can only import the songs into Rock Band 2 or use the poor interface the game comes with.
