Late on Thursday (June 3), the latest leaked track from Eminem’s eagerly-anticipated sixth album Recovery hit the Internet. “Won’t Back Down” is a powerful burner that features some shout-along verses from Slim Shady that bounce and dart all over a bottom-heavy, bluesy track built by DJ Khalil. Though some fans were skeptical of the fact that Pink was on the track, her rugged-but-pretty pipes add a great twist to the chorus. Past Emimem albums haven’t contained a ton of guest spots, so each and every tag-team Shady chooses is gone over with a fine tooth comb. But “Won’t Back Down” ranks up there with some of Eminem’s best recent songs, which means the team-up with Pink should be considered a gigantic success.
