Lyric discussion by tobeforgotten 

I think...that Black Thought..or Cody ChestnuTT, the narrator in general, is trying to leave his mark on the world. This is obvious, however, with "keep my legend alive." However, he's not just trying to leave his legacy of himself, but the actual legacy of music, more specifically, Rock & Roll.

However, he's..."fertilizing another behind my lover's back," thus making Rock & Roll the estranged child. Possibly noting the actual birth of Rock & Roll, which is 'the estranged child of Jazz'.

Absolutely brilliant song.

@tobeforgotten I believe you have nailed it. Thank you for doing so articulately.
