The world just doesn't feel right without any new Timbaland albums. The rapper/producer last released Shock Value II in 2009, and while there isn't going to be a Shock Value III, it only makes sense to revisit one of the best songs that Timbaland ever made. 'Give It To Me' was a track off the first Shock Value record and reached number one on the Billboard Hot 100. It didn't win its Grammy Award like it should have, but it doesn't change the fact that Justin Timberlake's part was as smooth as ever, while Nelly Furtado controlled the track's chorus like she's always done. Timbaland's verse was the glue on 'Give It To Me,' and we'd kill for a reunion song featuring all three again.

B.o.B (feat. Hayley Williams and Eminem) - 'Airplanes, Part II' (2010)

Minds were pretty much blown when B.o.B dropped 'Airplanes' in 2010. Before Paramore reached the masses, lead singer of Paramore, Hayley Williams, lent her vocals to the track. The song was even better than the rapper's first hit, 'Nothing on You' featuring Bruno Mars. As the single continued to climb the charts, B.o.B's album released with an 'Airplanes Part II' - a song with Williams, as well as Eminem. Odd combination? You bet. But it worked effortlessly. B.o.B. had all new verses on Part II, and while Williams' hook was unchanged, the real star was Eminem. His verse is up there with his best, and it's the ultimate proof that, regardless of genre, three is always better than one.
