Rihanna just dropped her highly anticipated collab with Kanye West and Paul McCartney titled "FourFiveSeconds." The acoustic single continues with the stripped-down aesthetic of "Only One," with McCartney once again handling instrumentation—this time on the guitar—and Ty Dolla $ign contributing background vocals. Both Kanye and Rihanna remind us of their DGAF mentality, allowing for the possibility that they might spaz out and end up in jail.

Kirby Lauryen, Mike Dean, Dave Longstreth, Dallas Austin, Elon Rutberg, and Noah Goldstein are also featured on the credits.
