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) 
sample in intro: Lauren Bacall (Movie: To Have and Have Not)
UPDATE - thanks Ouch for your tip and help also with artwork, and others for plays and listens
All those questions to that poor Demi !!
Sony simple delay on last drum hit to get a fade out.
Extended mental about one bar @4:04
Small timing fixes in Florida, and also in Demi Lovato.
Noisegate on Florida vocal against small artifacts. Both vocals are much louder (mastered?) than I used to, so I lowered their volume a lot.
EQ on Demi Lovato and I used only the cleanest sound parts of her acapella.
