Rihanna, Kanye West, & Paul McCartney "FourFiveSeconds" (NEW MUSIC)

Rihanna has released a collaboration with Paul McCartney and Kanye West, with the singer delivering an acoustic ballad and giving fans her first new material since single Jump almost exactly a year ago. The track Four Five Seconds was teased by West on Wednesday at the iHeartMedia music summit and follows his own collaboration with the Beatles songwriter earlier this month, Only One.

Four Five Seconds is a slower number in a departure from West and Rihanna’s previous collaborations All of the Lights (from West’s album My Beautiful Dark Twisted Fantasy) and Run This Town, where the pair teamed up with Jay Z.

McCartney has started 2015 with two unlikely collaborations. Four Five Seconds follows his contribution to the soundtrack of Destiny, one the biggest selling video games of 2014.
