Although Michael Cera and his Sex Bob-omb cohorts are ripped directly from the pages of the graphic novel the film is based on, their music is accumulated from obscure albums under the punk and garage rock section of a 1990's record store.

The guitars are fuzzier than moldy sour cream (but...in a good way?), but those rhythms are bouncy in all the right ways.

Alt-rock icon Beck wrote and composed every song Sex Bob-omb plays in the film, while his bandmate Brian LeBarton took up bass and drum duties on the tracks. But the three actors -- Cera, Alison Pill, and Mark Webber -- all sing on the tracks and learned to play their respective instruments for added realism in the film.

Best Song: "Threshold"

Brisk and frenetic, this is one of those songs that makes your leg start to shake without you realizing it. Besides, this is the song that helps Scott defeat two of Ramona's "evil exes", so that has to bump it up a notch.
