Update 3/17/08: Much better after DLC has been made available Fun, but song selection could be better.

Update 3/17/08: OK, after playing for several months and seeing all of the DLC that they have made available, this game ROCKS! Hours and hours of fun, and plenty of replayability. Some of the DLC songs are still a little to hard rock for my personal tastes, but still a fantastic game!

Probably the best party game ever.

--------------------------------------
Having been a huge fan of both Karaoke Revolution games for the original Xbox, I had really high expectations for Rock Band.
While the blending of KR with Guitar Hero and the addition of the drums are fantastic, the set list seems to keep this game down. Could be just my personal taste in music, but I'm really disappointed in the song selections.
I would love to see all of the old KR songs available as DLC! The guitar parts also seems harder to nail than Guitar Hero II. I will say, however, I really like the original versions of the songs, rather than the covers on nearly all of the KR songs. I'm sure that took considerably more work than producing the covers.
