Are Kanye West and Paul McCartney Working on New Music?

Aside from an early rough leak of 'All Day,' it's been mostly speculation about what to expect on Kanye West's upcoming effort. While that's in the works, there could be another West project coming up -- that one reportedly features Paul McCartney.

Page Six's sources say that the two are secretly working on a number of tracks, including one titled, 'Piss On Your Grave.' The Daily Mail previously reported that West was hoping to feature McCartney on the 'Yeezus' follow-up and the rapper was seen at McCartney's concert at Dodger's Stadium in Los Angeles last week.

A small portion of old school rockers seem to be fans of West. Elton John appeared on the outro to the star-studded 'All of the Lights' and the late Lou Reed of the famous Velvet Underground lauded 'Yeezus' in an essay for The Talkhouse.
