Artist: Kid Sister Track: "Right Hand Hi" Album: Ultraviolet Listen

Things apparently irked Kid Sister about her upcoming album, which was supposed to be released last year and now will drop Oct. 6 in irk-free form. This track and "Pro Nails," the Kanye West collaboration that appeared as a single last year, prove that it was worth waiting for the Chicago emcee to tweak some things.

"Right Hand Hi" at first sounds like a mash-up gone haywire -- a Future/Sex refrain, followed by an M.I.A. knockoff -- but the ways the two strains merge later on shows Sister's knack for welding multiple sounds.
