Rihanna isn't really featured on "Contemplate," the latest leak from Wale's Attention Deficit; instead, her "Question Existing" is sampled as the vocal hook for the moody track. "Contemplate" has more in common with the tracks on Mixtape About Nothing than the jocular tracks that have leaked from the album from thus far, which Wale fans will surely tell you is a very good thing.

Attention Deficit is due out on Nov. 3. [Nah Right]
