what are you talking about creed is a Christian band
No they aren't, or at least not based on what I've heard and seen on TV (which of course makes it true). I know that the lead singer's father is a preacher (or something) but I believe that he rejects most of his father's organized religion. I believe this is also the same situation with Collective Soul.
As far as music styles go, I personally don't like Creed at all, but everyone has their own tastes.
Edit: I should have read the entire thread before making the point that everyone has already made. My apologies!
