He's still promising, but his latest lyric doesn't even offer a vague time frame, In "Brooklyn (Go Hard)" (video; lyrics), Jay-Z promises, in unsurprising hyperbole, "Now when I bring the Nets, I'm the black Branch Rickey."

The song, by the way, was produced by Kanye West and is the first single from the soundtrack for "Notorious" (due January 13), a biopic of the late Brooklyn rapper Notorious B.I.G., according to Reuters.
