Image Credit: Mathew Imaging/WireImageWhen Saturday Night Live-skit-turned-big-screen-fandango MacGruber uncorks in theaters on May 21, it will do so to the soaring synthesizer chords of “Champion,” a triumphantly low-budge theme song from co-star Kristen Wiig (a.k.a. Vicki St. Elmo).

In true MacGruber form, the song—featuring the appropriately monikered U.K. collage-rocker Lightspeed Champion—sounds like it was put together with a Yamaha keytar, a portable mic, a ten-line rhyming dictionary, and a dream. (You can stream it for yourself over at Stereogum.)

The soundtrack’s other entries lean heavily towards velveeta ’80s classics (Toto’s “Rosanna,” Mr. Mister’s “Broken Wings,” Quarterflash’s “Harden My Heart”), with a few burly indie-rock garnishes (the Black Keys’ “Heavy Soul,” the Hives’ “Tick Tick Boom”).

What do you think, summer-movie soundtrack fans—MacGreat or MacBetterLuckNextTime?
