For a long time I've thought that the most hip-hop thing about Mary J. Blige's landmark 1992 album What's the 411? wasn't the at-the-time-unheard incorporation of boom-bap breaks into a sung R&B context, but Blige's cover Rufus & Chaka Khan's "Sweet Thing." A 21-year-old with a flat voice, a honking tone, and less than half of Chaka Kahn's range covering a classic displayed more bravado than anything else on the record. It was gutsy, raw, arrogant perhaps to the point of delusion, and it worked—for many, Blige's is the definitive version of that track, despite her vocal limitations. What that song lacks in technique, it makes up for in stunning self-assuredness.

Time for my first cigarette! Please rock the following jam on repeat until we return in like, ten minutes, which really is probably 30 minutes for you. 2009 had some pretty great #chairdancing songs. This is 2010's first great one.
