Probably not Sov's finest hour, but if for no other reason than kitsch value, you might want to click here to stream Lady Sovereign covering the Sex Pistols' "Pretty Vacant." The track is off the upcoming O.C. soundtrack of covers The OC Mix 6: Covering Our Tracks. Why this weird marriage wound up on the soundtrack is beyond me (like Seth Cohen listens Sov, or the Sex Pistols for that matter) but it sure beats Tally Hall (who?) covering "Smile Like You Mean It."
