Unfortunately, there is no option to expand Lego Rock Band's catalog through the Music Store, so you're stuck with only 45 songs on the disc to play through. Replay value is further hindered by a lack of online functionality, so you cannot challenge friends outside of your home. However, even with these omissions, this is another solid entry in the popular franchise. The charming visuals and goofy story make this a good place to start for Rock Band rookies, and the setlist is quirky enough for everyone else.
