  The song sung by the Lannister soldiers before the battle and played over the end credits, "The Rains of Castamere", was adapted from the ''A Song of Ice and Fire'' novels by the series's composer Ramin Djawadi. The end credits version was performed by the American indie rock band The National, and sung by their vocalist Matt Berninger. The song also appeared in at least two earlier episodes, in which Tyrion can be heard whistling the melody.
  According to the novels, the song is about Tywin Lannister's victory over vassals led by House Reyne of Castamere, who had rebelled against House Lannister, about 40 years before the events of the novels. The stanza of the song that was adapted for the series tells of the vassals' defiance-–"And who are you, the proud lord said / That I must bow so low?"–-and the subsequent obliteration of their houses: "But now the rains weep o'er his hall / With no one there to hear."
