Kanye West made most if not all of the beats for Common's "Finding Forever" album, and Common decided not to use the beat that is feature on "Everything I Am" hence the opening lyric of...
"Common passed on this beat, i made it to a jam"
So, it was intended to be a Common beat, yes.... but it's actually a Kanye West beat as he was the one who made it
Aside from that, Graduation was a MUCH better album than 50's new one, however, Chamillionaire's new album was VERY impressive. VICTORY!
