I don't really like Aerosmith either, but the band-focused game concept is interesting, and I think it foretells of what is to come.
I think the Beatles are overrated too, but they're still the best rock band in history.

A little overrating won't stop that. Just remember that they're more than "Love Me Do." They had an incredible evolution over those 8 short years. There's a broad catalogue of songs for a game like this.
John, Paul, George, Ringo!
