A Tribe Called Quest - Can You Kick It ? (instrumental) 
Florida - Whistle (acapella) 
Luis Fonsi + Demi Lovato - Echame La Culpa (parts of acapella, using both voices) 
samples in intro:
Otis Redding from album "Live at the Whisky A Go Go part 2" (and in Steinski's Lesson 3)
Lauren Bacall from movie "To Have and Have Not"
UPDATE - thanks Ouch for your tips and help, also with the artwork, DJ Axcess for the clean Whistle acapella, and others for plays and listens
WHAT I DID:
All those questions to that poor Demi Lovato !!
Sony simple delay on last drum hit to get a fade out, and extended mental one bar @4:04
Small timing fixes in Flo's flow and in Demi Lovato, who got dirtier by me around 3:00.
EQ on Demi Lovato and I used only the cleanest parts of her acapella.
Replaced my old Whistle (pella) with a clean one provided by DJ Axcess.
Rearranged the Bacall sample in the intro, and added an Otis Redding introduction, the famous whistler on the dock of the bay (a special joke for Ouch).
