In essence, Alison Carney's 2008 rendition of "You're Gonna Want Me Back" is a loose cover of not one, but 2 tracks: J Dilla - "Stop!" and Dionne Warwick - "You're Gonna Need Me Back." Seemingly performed @ the DC Dilla Tribute, Carney submits her take on Donut #6, "Stop!" ...which in turn, is a cover of Warwick's Just Being Myself-era composition. "You're Gonna Need Me (Dionne Warwick) and "Why?" (Jadakiss/Anthony Hamilton) are the 2 sampled elements that make up "Stop!"
Head on over to Who Sampled, to hear a side-by-side comparison of Dilla vs. Warwick. A small amount of additional Alison Carney info is view-able over @ aLIsoN WoNDeRLaND.
