Whether you love hip-hop, pop or classical, everyone knows a good riff, and no one's created as many intensely catchy ones as Quincy Jones. Famed for producing all-conquering pop in tandem with Michael Jackson, Jones has also been sampled by artists such as M.I.A. and 2Pac. His swinging jazz sensibilities and groove-centric rhythms are perfect foils for a plethora of artists to anchor their songs.
