Lupe Fiasco's latest song, 'Lightwork,' is an electro-hop track built around the Bassnectar remix of Ellie Goulding's 'Lights.'

Generally, when rappers borrow from a pop song, they use the sample as a hook to break up the monotony between verses -- but Fiasco takes a completely different approach on 'Lightwork.' The track opens with a full minute of the sped-up, remixed Goulding track and closes with 30 more seconds of the sample.

In between, Fiasco spits rhymes for three minutes without any breaks. The Chicago rapper touches on a number of subjects, including his own touring life and success: "Me and my band out on that road / On a never-back-down-from-a-stance tour / Yeah, touch more souls than a dancefloor / While they touch less tours than a hand or / Ceiling fan or wait, let me tell ya slower / Lift my fans up to the to the ceiling / And you’ll never touch the floor."

Later, he seems to address his recent album, 'Lasers,' which surprised some listeners with its bold political statements: "I know that don’t mix, like ecstasy and ketamine / Funny how I’m only sick if you never catch a thing / Argue with your friends over what really the record means / Back and forth about its course, with professors refereeing / Why he so rebellious? Up-front with his realness? / They wanna be Fiascos, reproduce his failures."

Fiasco has never stuck to the traditional hip-hop formula, and the engaging 'Lightwork' further validates his willingness to experiment. The song does not appear on 'Lasers,' but is instead said to be targeted for an upcoming mixtape.
