Paul McCartney, Kanye West and Rihanna team up on new track

It follows another Kanye x Macca endeavour, "Only One", the apparently first of many collaborations between the two. There was a rumour swirling that McCartney was co-producing all of Kanye's new album - the follow-up to 2013's Yeezus - but this has been denied by reps from both camps.

However, it could feature Rihanna's long-awaited Unapologetic follow-up, codenamed R8, which is widely expected to drop this year.

Kirby Lauryen, Mike Dean, Ty Dolla $ign, Dave Longstreth (Dirty Projectors), Dallas Austin, Elon Rutberg, and Noah Goldstein also all feature in various capacities on "FourFiveSeconds", as Stereogum note.

You can listen to the star-studded collab via Rihanna's website, or purchase it via iTunes.
