Game of Thrones doesn't always feature music, but when it does, it's memorable. Most recently, Icelandic group Sigur Ros dropped by on Season 4, Episode 2 ("The Lion and the Rose") to cover “The Rains of Castamere" during the royal wedding.

Joffrey (Jack Gleeson) petulantly cut the group off during the festivities, but if Joffrey doesn't like something, that normally means it's awesome, and this was no exception. While we love the  The National's version of the Lannister song, Sigur Ros's melancholy take is a good addition to any Game of Thrones fan's show playlist. As band member Georg Holm said, this might just be the "gloomiest" version of the sinister song yet.

Want to add it to your music library? Good news: it's available for download! You can get it at iTunes and Amazon, or you can steam it on YouTube. It will also be available as part of the Season 4 soundtrack, which will be released digitally on June 10 (and on CD on July 1, if you still prefer a hard copy).

Game of Thrones airs on Sundays at 9 p.m. ET/PT on HBO.
