Rihanna drops her highly anticipated collaboration "FourFiveSeconds" featuring Kanye West and Paul MaCartney. It follows the same formula of 'Ye's first collab with McCartney "Only One," a very stripped-down sound. This single could be the record Kanye previewed at the iHeartMedia Music Summit at Burbank, Calif.’s iHeartRadio Theatre. At the conference the song previewed was described as “acoustic guitar and a big, soaring chorus and melody with a massive hook.” Sure does sound similar.

This is the collaboration Ty Dolla $ign was referring to also. Names also credited for the song are Kirby Lauryen, Mike Dean, Dave Longstreth, Dallas Austin, Elon Rutberg, and Noah Goldstein. Listen to "FourFiveSeconds" below and download it here. Leave your thoughts in the comments. Judging from the cover art, it looks like denim is the trend to watch this Spring.

Rihanna is very happy.
