The Roots' drummer Questlove is preparing to release a new memoir, "Mo' Meta Blues: The World According to Questlove."

The book, co-written by Ben Greenman, editor at the New Yorker, includes some footnoted commentary -- penned by Rich Nichols -- that is attracting some controversy prior to the release.

Nichols, manager of the Roots, offers his insight into 2 Chainz's most recent album, Based on a T.R.U. Story.

"It's a f---ing object lesson in thematic narrowness, one dumbass idea repeated over and over again," Nichols reportedly wrote. "There's a song called 'Crack' and then a song called 'Dope Peddler,' right next to each other. Then a little later there's a song called 'I Luv Dem Strippers.' I'm not knocking 2 Chainz, but what kind of market elevates him like that, at the expense of everything else?"

Perhaps most interesting about this excerpt is the fact that the Roots have been signed to Def Jam Records for a long time. Def Jam was the label that put out Based on a T.R.U. Story.
