Following rumblings this week that Kanye's new single with Rihanna and Paul McCartney was very soon to dropping, here it is! You can stream "FourFiveSeconds" on Rihanna's site. The stripped-down acoustic guitar track features several collaborators, including Ty Dolla $ign and the Dirty Projectors' Dave Longstreth and will either be included on Rihanna or Kanye's new albums. Seeing as Sir Paul and Kanye have already collaborated for a similarly softer-side-of-Yeezy single, "Only One," we'll go with the latter. #AllDay.
