Rappers' albums being pushed back

Examples: Young Jeezy's Thug Motivation 103, Juelz Santana's Born to Lose, Built to Win, Lil Wayne's Tha Carter III

You might be a rapper if... you promised that your collection of songs would definitely, absolutely, unquestionably debut on a certain date, only to have that date come and go—thanks to cold street singles, rappers delivering their verses late, and the label getting cold feet. And you definitely are a rapper if your excuse for the push-back is: we couldn't clear the samples in time.
