"Lost Cause" is from Beck's 2002 album Sea Change, which marked a departure from his style in favor of a folk rock sound (I'm taking this from Wikipedia, though this will be my first Beck album to listen to when I get the chance). The album's theme centers around that of deteriorating relationships, and that is visible in the song's lyrics (coming up soon). Rolling Stone magazine gave Sea Change a five star rating and placed it number 440 on its list of the 500 Greatest Albums of All Time.

"Your sorry eyes, they cut through bone/They make it hard to leave you alone/Leave you here wearing your wounds/Waving your guns at somebody new."
The music video off YouTube I've included is, well, entirely in slow-motion, with Beck's head attached to some type of humanoid torso and sparks and stuff. Well, hope you enjoy this song as much as I did (the video, meh).
