A song that should have been on the Beowulf movie soundtrack

The song? Grendel's Mother by the Mountain Goats. Permanently residing in the soundtrack that plays all day in my head courtesy of the evil genius who composes the Chaucer blog. Angelina Jolie, eat your heart out. Or rip out and devour the heart of Hondscio, or whatever disposable member of Beowulf's retinue you please.
