Collaborations were a hit in 2014 and this Grammys 2015 nominees list for Best Pop Duo/Group Performance recognizes those awesome musical concoctions!

Who wouldn't recognize the earworm "Bang Bang" by Jessie J, Ariana Grande and Nicki Minaj? Or Iggy Azalea and Charli XCX' "Fancy" duet?

A Great Big World and Christina Aguilera's "Say Something" brought millions tears and Coldplay's "A Sky Full Of Stars" was one of 2014's biggest hits as well.

"Dark Horse" by Katy Perry featuring Juicy J also became the anthem to a lot of people last year.
