Jon Snow’s rocker about Wildlings is sung to the tune of exactly the right Troggs song. There’s an unsettlingly jaunty ditty about the Red Wedding. Daenerys Targaryen takes a stab at reggae. Jaime Lannister actor Nikolaj Coster-Waldau’s incest-inspired ballad puts Michael Bolton to shame. But Peter Dinklage’s musical tribute to Tyrion, “A Man for All Seasons (Still Goin’ Strong),” is definitely the one you’ll want on your iPod.
