Some of 2013's best music was a result of musical superpowers joining forces. If one hit-maker can produce an amazing track, two or more hit-makers is an almost guaranteed recipe for success. The Grammy for Best Pop Duo/Group Performance honors such collaborations. This years nominees are Daft Punk Feat. Pharrell Williams, ‘Get Lucky,’ Pink Feat. Nate Ruess, ‘Just Give Me a Reason,’ Rihanna Feat. Mikky Ekko, ‘Stay,’ Robin Thicke Feat. Pharrell Williams + T.I., ‘Blurred Lines,’ and Justin Timberlake Feat. Jay Z, ‘Suit & Tie.' Who do you think should take home the Grammy?

One of the biggest hits of the summer was Daft Punk's 'Get Lucky,' featuring Pharrell Williams. The duo electronic sound melded perfectly with the rapper/producer's smooth vocals. The result? A warm weather-ready jam that celebrates seizing the moment.

Pink hit a poignant note with 'Just Give Me a Reason,' her duet with fun.'s Nate Ruess. The ballad featured the singers representing opposite sides of a broken relationship. Their voices work together, forging a truly emotional track.

Rihanna is known for her club jams, but she wowed fans with her unexpected -- and great -- ballad, 'Stay.' The duet, featuring Mikky Ekko, lets Rihanna's vocal talents shine. We rarely see her in this emotionally stripped-down mode, but we think the piano ballad is a definite win.

One of the biggest and controversial songs of the year was Robin Thicke's 'Blurred Lines.' The single, featuring the talents of Pharrell and T.I., toed the (blurred) line between provocative and over-the-top. Nevertheless, the track became a massive success.

These days, anything Justin Timberlake touches turns to gold. Throw in Jay Z, and you've got a solid hit. 'Suit and Tie' celebrated JT's return to the pop scene, but also upped the music game for other singers.
