Think Justin Bieber slowed down 800 times was cool? Try Jurassic Park, slowed down a thousand percent. John Williams' epic dino theme isn't exactly pump-up music at this speed, but it will lull you into a sublime Jeff Goldblum trance.
Although it lacks the ghostliness of Bieber's comatose vocals, audio manipulator Birfeeder's super slo-mo rendition makes me think of velociraptors moving extremely slowly, which is perhaps even cooler. And at almost an hour long, it'll be just the thing to listen to before you fall asleep, or majestically run from a very slow triceratops.
