So they put a few tracks recorded for the Black Jack Johnson LP on the album, together with a few hip hop tracks that are cool for a mixtape, but definitely not album material.
Maybe he thought "okay, i'm gonna give them their album now, they'll buy it anyway, so I'm gonna take a look at my demos and put that ish together" or the label did that. Who knows?

by the way:
why does the uk get "the jump off" as a bonus cut?

The idea of putting one album out instead of one rock album with Black Jack Johnson and one hip hop album as Mos Def is just stupid. Rockheads will not notice the Black Jack Johnson tracks, Hip Hop Heads will hate them, I could go on and on.

Time to listen to the wonderful BOBS again.

I'll buy it anyway (two times on vinyl and one cd, same thing with the re-release without "the rape over"), because I'm a one of the stupid Mos Def nerds around there that wants to have everything.
