I'd rather have my little kids listening to Led Zepplin or some Dave Matthews. Maybe with some Crosby, Stills, Nash, and Young mixed in.
But as far as giving him credit for not cussing. Not going to do it. Music is supposed to be art, and you're not supposed to hold back during the creation of art. If Will Smith wants to do his thing without "profanity", then by all means do it. But when he tries to wear that as some badge of honor all I see is a gimmick to get suburban America to buy more of his records.
