It's their cover of Sigur Rós' Ný Batterí off of the "Ágætis Byrjun" album. I might not like Geoff Rickly's voice on this song, but I have to give him credit for singing in the original Icelandic language. That's awesome. So, go and download this song. I recommend it to anyone, really. It's an easy song to listen to. Probably won't find it in stores, since I believe it's only appearance was on an import of War All The Time (I think) and an Island Records Comp. CD. So... download it.
