Promoting the fifth season of the HBO institution and featuring samples from the series' fourth season, the release is available as a free download right now.

Among the artists recruited for the free release are rappers Method Man, Snoop Dogg and Talib Kweli, heavy rockers Killswitch Engage and Mastodon, and singers Ty Dolla $ign and Estelle.

Track names go from hyper-literal (Snoop Dogg's "Lannister's Anthem," Mastodon's "White Walker") to the thematic interpretations (MNDR's "Run for Cover").
