Allan Kingdom showed us what the power of a Kanye co-sign can do for an up-and-coming artist. But Mr. West is also capable of reaching into the past to mine new material. Exhibit A: Paul McCartney. Exhibit B: Madonna, who just confirmed an appearance on Kanye’s So Help Me God album.

“He wanted to rework my whole album, but forgot he had like 20 other projects to do,” she said in an interview with Complex TV. “We ended up working on four songs for my album, and then we wrote another that will be on his.” It’s shaping up to be an interesting 2015 for Madonna, a year that’s already produced this collab with Chance the Rapper and Mike Tyson.
