Eminem leads the way on this hard-hitting soundtrack, with two new songs worthy of his staggering catalog—the dizzying, Gwen Stefani-assisted torrent “Kings Never Die” and the haunting title cut. Elsewhere, some of rap’s most reliable and exciting names reign supreme. While 50 Cent delivers a cold-blooded hook on “Drama Never Ends,” Action Bronson and Joey Bada$$ team up with Rico Love for the moody, rain-spackled R&B hybrid “What About the Rest of Us.”
