So I guess my statement of Popular = Cool was false. I should have said "Something being cool makes it popular".
Bu is has to be "cool" for the general population to become popular. On the other hand, personally I find everything too popular uncool, as SG stated. Some people want to stand out.
I'm not into christian music, but would take it over any mainstream music any day. Mainstream music is probably "cool", but that's the only good thing about it.
Also, it depends how you define christian rock bands, but some of the "normal" rock bands are actually christian rock bands without us noticing it. Can't think of any now, though

EDIT: Whoops, noticed there were more pages and the topic has changed a bit. Sorry about that.
