Please excuse my extremely long title (that I could have shortened but decided not to) about NBA player's trying to sing R&B and rap

I saw him (Kereem Rush) on 106 & Park yesterday. I guess he's a retire NBA star or something? Anyway, why do all the Lakers think they can sing and rap?

Ron Artest made a song called "Champion"

His song isn't that bad though. In fact it's kinda good.
