Kanye West is starting the new year with a new song.
The rapper released "Only One," a collaboration with Paul McCartney, on his website and iTunes on Wednesday.
The ballad, featuring McCartney on keyboard, is sung from the perspective of West's late mother, Donda West.
"My mom was singing to me, and through me to my daughter," West said in a statement (via Rolling Stone), also noting that the name "Kanye" means "Only one."
West and McCartney began work on the track early last year in Los Angeles, a press release said, as part of "a simple brainstorming session between the two: With McCartney improvising on the keyboards and Kanye vocally sketching and shaping ideas in a stream-of-consciousness riff."
And there could be more collaborations coming from the duo -- a spokesperson for West called "Only One" the first "publicly available recording from what has become a prolific musical collaboration between these two legendary artists," according to Rolling Stone.
West's wife, Kim Kardashian, also noted that "Only One" is her favorite song by her husband.
