Aerosmith will sell just fine. Just because a small group of pinsiders are very passionate on their like/dislike for particular rock bands, it doesn't mean diddly. Aerosmith is one of the top selling bands ever and will be a big draw - and Stern knows this.
They have more US album sales (67 million) than ANY of the other suggested bands except the Beatles and Led Zeppelin - which Stern probably can't get the licensing for. It's kind of hilarious how many people keep suggesting B-level heavy metal bands like they would have a shot at selling in volume for a pinball machine over a mega popular band like Aerosmith.
Some of the negativity is probably spurred on by a dislike that Steven Tyler was on American Idol - but from a marketing perspective, Steven Tyler / Aerosmith is mega popular right now and will result in more sales because of American Idol.
Bring it on Stern! The naysayers are just a small, insignificant (but vocal) sampling
