The Get Rich or Die Tryin track 'Blood Hound' was originally a Young Buck track.
But 50 liked it for his album and ended up leaving Buck's verse on as a feature.
Buck explained how it went down.
"Out of nowhere, bro I got this call bro, from Sha Money bra, through Cee-Lo," Buck explained. "Sha Money just called and asked about some record you was playing. 50 wants to buy that record and put it on his album ... I don't even know what to ask for it. But I was like, hell ya, let's do it ... That was a record I already had, it was mine. 50 basically just kept one of the verses and added two verses."
Buck went on to say that when 50 learned during the negotiation for "Bloodhood" -- which he says he wrote in ten minutes -- that Buck didn't have a record deal, he made him another offer to join G-Unit.
"That record changed my life, 50 gave me an opportunity to be on G-Unit off that record," Buck explained.
