Now we're getting somewhere. What is more important, how much money they make, or how much they play the game, (even if unsuccessfully).
I think any artist who spends more time worrying about clothing, hair, makeup, or videos, than actually writing songs or performing is a sellout.
Therefore all these image conscious bands like KORN, Slipknot, and such are sellouts in my opinion.
What's more interesting, is the artist's that make the question more philosophical. Like are failed pop acts like B4-4, who don't catch on, and never make any money still sellouts.
Or better yet, what about Everclear. Art spends a great deal of time playing "the game" promotion wise, and sells alot of records. Yet his music hasn't changed that much, and he's not really image concious. Is he a sellout because his music is popular, or because of the promotion he does? And doesn't the motivation mean something? Some acts do alot of promotion because they're genuinely proud of thier record, and want it to be heard.
