Daughter North, late mom inspired 'Only One'

"Only One," a collaboration between Kanye West and Paul McCartney, has been released exclusively on iTunes, Def Jam Recordings announced Thursday.
The song is the debut single from West's forthcoming solo album and the first of several of West's surprise recordings with McCartney to be released.
"In early 2014, Paul McCartney and Kanye West first began working together in a small bungalow in Los Angeles," the record label said in a statement.
"The process that would result in 'Only One' began with 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," the label said.
"My mom was singing to me, and through me to my daughter," said West, whose first name Kanye means "only one."
