Have you checked the most current Billboard chart? Creed sold what....6-7 million copies of My Own Prison. I'm not wishin em bad luck or anything....but the charts ain't lookin too good.
If its fun for them, then so be it. I'm glad they are having fun....but I would think that at some point...it would have to become a profitable situation.
P.S. Oh.....I don't own any Metallica either. See, my taste in music is very different from yours.
