Luigi's right about what he said. I agree. Now to respond to the Aerosmith thing: I agree it was sort of a put out to see them performing with nsync, especially to a guy like me who is a giant Aerosmith fan. But I don't lose respect for them because of it. Why wouldn't they want another chance to speak to the population? And if even one person in that audience who was brought up on Britney Spears and the Backstreet Boys saw Aerosmith rockin' and decided to give them a try and buy a CD, wouldn't that make it worth it?
Also bear in mind that rockers performing with 'poppers isn't an unusual concept. It happens a lot. I remember with a shudder that cover of Kashmir (Zeppelin) done by Puff Daddy, and Jimmy Page played along on the video. No recognition was given to him in the video as the original writer, it was just a few seconds of him playing his Les Paul for novelity sake. And what about Sting performing "I'll be Watching You" at the Grammy's, again with Puff Daddy. It happens a lot.
