Samples, references, and rip-offs

”HAPPY” Ashanti: Fishing for an old-school sample, this young chanteuse comes up with an outstanding one: the 1982 Gap Band track ”Outstanding,” to be exact. Nice — although we keep wondering what her cover of the Rolling Stones’ ”Happy” might have sounded like.

”WHERE’S YOUR HEAD AT” Basement Jaxx: This ubiquitous club rave-up samples not one but two Gary Numan songs, ”M.E.” and ”This Wreckage.” Give ’em bonus points for steering clear of ”Cars.”
