Kanye West rang in the new year with a brand-new song, a bittersweet ballad titled "Only One," the first released music from his long-rumored collaboration with Paul McCartney.
McCartney plays keyboard on the simple, poignant song that is written as a letter from West's mother, Donda, who died in 2007.
The song is meant to be a message to West's young daughter, North.
West's wife, Kim Kardashian West, praised the song on Twitter, telling fans, "People always ask me what my favorite Kanye song is and it's Only One. Kanye feels like his mom sang thru him to our daughter."
The single, which was released on West's website and through iTunes, is the first song from what has been described by West's reps as "a prolific musical collaboration between these two legendary artists."
The song is from West's forthcoming untitled album, his first since "Yeezus" in 2013.
