BIGGIE feat. Sadat X
This eventually found the light of day on B.I.G.'s Born Again album, but that version doesn't come close to this one. This is that Ready To Die BIGGIE.
LL Cool J
Obviously not the real title, but this song is unknown. It also sound pretty shitty. My guess is that it was a record he was working on and then scrapped.
De La Soul
This one is basically a De La version of Chi Ali's "Roadrunner".
The Roots
Produced by J Dilla.
Mobb Deep
This one came courtesy of Stretch Armstrong. The Beatnuts remix to the original "Shook Ones" that never saw an official release.
