Producer: Erykah Badu, Tone da Backbone

The Shaft soundtrack's "Bumpy's Lament" is home to one of the most famous guitar licks in music. It was used on the original album version of Erykah Badu's "Bag Lady," and had also been used a year earlier on Dr. Dre's 2001 anthem, "Xxplosive." Someone got the brilliant idea to blend Badu's track with the much harder-hitting instrumental of Dre's record, and magic was created. The "Cheeba Sac Mix" was the version sent to radio, and the version used in the music video for Badu's single. In turn, Dr. Dre's steroids-enhanced production boost helped "Bag Lady" shoot to No. 6 on the Billboard Hot 100. —Ernest Baker
