Let me think about it...no!
The day they put in one of the crap forced Disney Channel "stars" is the day I lose faith in the musical taste of humanity for good. Justin Beiber was already an assault on my sanity that I barely survived.
But seriously, Aerosmith is an amazing rock group no matter what you think of the members or their music. They're right up there with GNR, Scorpions, etc. in that they've had a lasting and noticeable impact on mainstream rock. If they had to replace Aerosmith, I don't think I'd want to see any of the modern bands on there,
as none have really struck me in the same way most of the artists from the 70s and 80s did. You can replace them with Metallica, I'd be all on board for that. Battery would go well with the ride.
