This rocker was produced by Danger Mouse, who is best known for being one-half of Gnarls Barkley. Originally Danger recruited the Keys to write and record tracks for R&B legend Ike Turner, a project that eventually was scotched following Turner's death. This was one of the songs originally recorded by Turner before he passed away.
"We Are Never Ever Getting Back Together" by Taylor Swift earned an entry in the 2014 edition of the Guinness Book of Records for the fastest-selling digital single. It reached the #1 spot on iTunes just 50 minutes after its release.
