Kanye West Premieres 'Only One' Featuring Paul McCartney

Kanye West has finally revealed his long-rumored collaboration with Paul McCartney.

(Listen to "Only One" here.)

The song is told through the perspective of West's late mother, Donda.

It's unclear as to if the song will appear on West's forthcoming album and is billed on iTunes as a single.

In September, Kanye collaborator Theopilius London hinted that West's new album was complete and tweeted the following:

""I Only remember kanye playing his new album 3 times in a dark room of 20 people last night and moshing drunk with mad babes haha"

In July, West told GQ Magazine that the album would be out in Fall 2014.

A rough version of the single "All Day" was leaked this summer, and has since been taken down. Of that song, West said the following:

"Even lyrically, I think about certain lines that I say on my new single, which is called "All Day," that usually Jay would say, but Jay's not on there. So I say, All day, nigga, it's Ye, nigga. Shopping for the winter, it's just May, nigga.

Ball so hard, man, this shit cray, nigga. You ain't getting money unless you got eight figures. Right? Jay would have said that."
