"Death To All Hipsters" is a track available on the Original Score for the Scott Pilgrim vs. The World movie. Most of the score was done by Nigel Godrich, but this particular track is credited to "Beck & Nigel Godrich." It's only 41 seconds long. I believe Nigel basically took one of Beck's Pilgrim tracks, and made a fast electropunk version of it, and that otherwise Beck is not part of the track beyond being a writer. (That's just a guess though.)
A short trailer for the movie remixed "Death To All Hipsters" into another short track called "Hey!"
