G-Unitleader 50 Centhas questionedP Diddy's contributions to hip-hop, and believes he uses ghost-writers.

He told Nancy B: "You know what's interesting, he's not an artist. An artist would be somebody that actually wrote something, maybe on the record or because we have R&B artists that don't actually write music, maybe it's unfair because of the pressures people put on me. Imagine if I just sat around and listened to people's CDs and say I'm just gonna say the first verse I hear that sounds good.

"That would completely take away the pressure and I would still be the artist in front of you with a new song every two minutes because every artist that has a song that would like to make some money off it would send it. It doesn't make you special.”
