Earl Sweatshirt wasn't happy that his new album, I Don't Like S---, I Don't Go Outside, leaked ahead of its release this week, but he didn't take it out on fans. Instead, he and fellow rapper Action Bronson (who just released his own album, Mr. Wonderful) teamed up for "Warlord Leather," produced by the Alchemist and sporting background vocals by none other than Lou Diamond Phillips. The track kicks off this week's installment of Mandatory Music – one that also features, Pfarmers, a new supergroup featuring members of the National and Menomena.
