• The original version of Back Down was a diss towards Ja Rule, Jay-Z, R. Kelly, Nas, Cam’ron, Irv Gotti, Supreme & Jermaine Dupri
• The Intro on the album was originally a completely different, full track. But Dr. Dre told 50 to change it because it was too dark
• If I Can’t was originally a solo Dr. Dre track
• What Up Gangsta, Many Men, High All The Time, Blood Hound and Poor Lil’ Rich were recorded before 50 signed to Shady/Aftermath
• Like My Style was the last song recorded for the album
• The album recouped fully in 1 month
• Many Men was originally a Dipset song. Then Nas recorded to it. 50 then heard the track in a session in 1999 with Nas and got the producer, Digga, to burn him a CD with the beat and kept it - the song was also finished long before 50 signed to Eminem and Dr. Dre
• The sample used on 21 Questions was the last ever sample Barry White cleared himself when he was alive
• 50 Cent originally sung the hook himself on 21 Questions
Edit: Damn, whoever runs that page actually came through and leaked the original version of 21 Questions:
