Los Angeles: Rihanna, Kanye West and Paul McCartney have collaborated for new track 'FourFiveSeconds'.
The soft and acoustic track is available at RihannaNow.Com, reported Rolling Stones magazine.
"I think I've had enough," sings Rihanna over the percussion-less, acoustic guitar-driven track.
"I might get a little drunk. I say what's on my mind. I might do a little time. 'Cause all of my kindness is taken for weakness."
West takes over on vocals, crooning, "Woke up an optimist. Sun was shining, I'm positive. Then I heard you was talkin' trash. Hold me back, I'm bout to spaz." West and Rihanna handle all of the song's vocals, duetting on the chorus with McCartney providing keyboards on the song.
McCartney and West had released their surprise collaboration 'Only One' three weeks ago.
