1. "Hangover" by Psy, featuring Snoop Dogg

Korean sensation Psy partnered with rapper Snoop Dogg for his third international single, "Hangover" (following 2012's "Gangnam Style" and 2013's "Gentlemen"), which marked his first time collaborating with an American artist. The music video for the Korean-English track made its world debut June 8 on Jimmy Kimmel Live! Currently, the K-pop star's viral hit "Gangnam Style" holds the record for the most-viewed YouTube video of all time, having garnered more than 2 billion views over the course of two years.

2. "Flawless (Remix)" by Beyonce, featuring Nicki Minaj

Two of music's female powerhouses joined forces for a remix of Beyonce's single "Flawless," originally from her self-titled visual album Beyonce (which took the industry by storm when it dropped on iTunes with no prior announcement in December 2013). Though the original single stirred controversy for its feminist themes, the remix version garnered attention for Beyonce's reference to the elevator scuffle that occurred between Jay Z and sister Solange earlier this year.

3. "Sing" by Ed Sheeran, featuring Pharrell Williams

The lead single off of the singer-songwriter's Grammy-nominated album x, "Sing" was penned by both Sheeran and Williams and produced by Williams. The "Happy" singer, who worked with artists such as Justin Timberlake, Alicia Keys and Miley Cyrus on his own album Girl, also contributed background vocals to the track (though uncredited).

5. "Bang Bang" by Jessie J, featuring Ariana Grande and Nicki Minaj

The female trio brought back a powerful pop collaboration reminiscent of 2004's "Lady Marmalade," performed by Christina Aguilera, Lil' Kim, Mya and Pink, with this uptempo anthem from Jessie J's third album, Sweet Talker, and the deluxe edition of Grande's album My Everything. "Bang Bang," which debuted at No. 6 on the Billboard Hot 100, is in the running for the best pop duo/group performance Grammy.

8. "Fancy" by Iggy Azalea, featuring Charli XCX

In this year alone, Australian rapper Iggy Azalea has teamed with the likes of Jennifer Lopez, Rita Ora, Ariana Grande, Jennifer Hudson, Ellie Goulding and mentor T.I., but it was her collaboration with Charli XCX that brought her debut studio album The New Classic to new heights.

9. "Dark Horse" by Katy Perry, featuring Juicy J

Since then, it has earned the title of YouTube's most viewed music video of the year with more than 700 million views, and the single itself placed second on Billboard's year end ranking for 2014. The song is also vying for a Grammy for best pop duo/group performance.

10. "Ew!" by Jimmy Fallon featuring

The late night host and the Black Eyed Peas frontman put a musical spin on The Tonight Show's comedy sketch "Ew!" for a collaborative single that debuted at No. 26 on Billboard's Hot 100.
