If you haven't heard 50 put out a diss to Diddy called "The Bomb" with the Dead Prez beat to hip hop.  I don't know what 50s deal is but he is whack.  I mean sure Diddy ain't shit as far as being a rapper is concerned but 50 has dropped off too.  I don't know why he's tryin to start a pointless beef between two weak rappers and using a dope beat to make his diss try to sound hot.
