J. Cole's feature on the 21 Savage track "A Lot" was notable for his shout outs to Tekashi 6ix9ine and Markelle Fultz and his accusation that some of your favorite rappers are faking their streams.
But you'll get none of that if you ordered the CD for i am > i was. (Apparently, people still do that.) That's because there is no J. Cole verse on "A Lot."
Instead, there's a third Savage verse, which you can listen to here.
Speculation is that it was cut from the CD. But it seems more likely it's the other way around: Cole's verse came in too late to be pressed on the compact disc, but was able to be included for streaming and digital downloads.
