Kanye West is starting off 2015 on a sweet and solemn note.
The 37-year-old hip-hop star pays tribute to his and wife Kim Kardashian’s 1-year-old daughter North West and his late mother, Donda West, with a ballad titled “Only One,” a collaboration with Sir Paul McCartney.
The single was released on iTunes on Wednesday night, New Year’s Eve, and its lyrics were penned with the perspective of Kanye’s mom, who died at age 58 in 2007 after undergoing plastic surgery.
