"FIRST GLIMPSE AT MY NEW MUSIC!!!" Rihanna tweeted on Saturday (Jan. 24) when she released a new track, featuring Kanye West and Paul McCartney, called "FourFiveSeconds."

The song, off her forthcoming eighth studio album, is a departure from 2012's Unaplogetic. A plucky acoustic guitar complements Rihanna's vocals. "I think I've had enough/ Might get a little drunk/ I say what's on my mind/ I might do a little time," she sings on the opening lines of the track. "Cause all of my kindness/ Is taken for weakness."

For Kanye's part, he sings, "Woke up an optimist/ Sun was shining, I'm positive/ Then I heard you was talking trash/ Hold me back/ I'm about to spazz."

Later, on the chorus, Kanye and Rihanna harmonize together, "Now I'm four, five seconds from wildin'/ And we got three more days 'till Friday/ I'm just tyring to make it back home by Monday morning."
