7. Drake f/ Rihanna "Take Care" (2011)
Album: Take Care
Producer: Jamie xx, 40
Drake prides himself on being transparent in his music, so when it came time to find a collaborator for this tale of complicated romance, he called on the girl with whom he's assumed to share a comparable history. Never one to back away from a challenge, Rihanna throws her heart into the chorus with some of her best vocal work to date. The crux of the record is held within her lines and she delivers them with an efficiency and honesty that makes "Take Care" a standout in both her and Drake's catalogs.
