The line between hip-hop, pop and electronic music is becoming increasingly blurred, as artists from each respective genre continue to cross over and collaborate with each other. In the past year alone, we've been treated to several rap features on pop and electronic tracks, thanks to artists like Taylor Swift, Kendrick Lamar, Jamie xx and Young Thug.

Check out a few of our favorite cross-genre collaborations from the past year.

Madonna ft. Nicki Minaj - "Bitch I'm Madonna"

Okay, jury's still out on how we actually feel about Madonna's fist-pumping ode to herself, but we will say that Nicki Minaj drops in for a solid cameo on the song. And she appears in the star-studded video, along with other guests like Beyoncé, Kanye West, Chris Rock and Katy Perry.

Dave Guetta ft. Nicki Minaj, Bebe Rexha, Afrojack - "Hey Mama"

Nicki Minaj is becoming the go-to rapper for EDM features. She's previously worked with David Guetta on "Turn Me On", and this year they linked for "Hey Mama" from his recent album Listen. For the video, they went all "Mad Max" crazy, and they're currently going over 67 million streams strong.

Ed Sheeran's 'Trap Queen' cover

Fine, so technically this isn't a rap feature, but there's no way I could complete this list, without including Ed Sheeran, who's unexpectedly recorded music with artists like the Game and Yelawolf, and casually does the most amazing rap covers. We're just waiting for him to get this all together on one record.

Arian Grande ft. Big Sean "Best Mistake"

This song might be even sadder since Ariana and Sean recently decided to call it quits on their relationship, but at least they made some magic while it lasted. On "Best Mistake" from Ari's second album My Everything, the Detroit rapper adds an emotional verse about love, family and all that could be. We even got to see them duet the song live.

Sam Smith ft. A$AP Rocky "I'm Not The Only One"

The original version of Sam Smith's heartbreaking love song was perfect to begin with, but maybe he just wanted to add a little extra flavor. And reaching out to A$AP Rocky was the right move. The Harlem rapper added two verses to the track without altering the vibe. Instead he just sprinkled a little extra reality on top.

SBTRKT ft. A$AP Ferg - "Voices In My Head"

A$AP Ferg has blessed us with plenty of club bangers on his own records, but when he teamed up with SBTRKT for the British producer's Fall 2014 album Wonder Where We Land, he hit a completely different stride. Over the woozy and slightly psychedelic track, we get to hear the Harlem rapper battle some of the voices in his head. And his flow didn't falter.

Taylor Swift ft. Kendrick Lamar - "Bad Blood"

By now you might've heard that T. Swift is a dedicated K.Dot fan, so it was only a matter of time before they worked together. Kendrick is featured on her hit "Bad Blood," but when the video finally premiered, it felt more like Kendrick featuring Taylor, since he had such a huge role, and I'm not mad at that. At all.

SBTRKT ft. Raury "Higher"

SBTRKT gets double the love on this list, since he was one of the first musicians to see how talented ATL newcomer, Raury, is. Raury told MTV News that he had long discussions about music and life with the U.K. producer, and eventually their connection resulted in this standout called "Higher."

Jamie xx ft. Young Thug and Popcaan - "I Know There's Gonna Be (Good Times)"

Jamie xx's new album In Colour features 10 smooth and hypnotic electronic tracks, with plenty of bass and even hints of steel drums for good measure -- and then there's this jam. Three and a half unexpected minutes of breezy, reggae-tinged fun, that should be on repeat for the entire summer. You can thank me later.
