It's not that the song wasn't recorded well, but that the vocals have a lo-fi effect on them, resulting in a slightly static-y sound and lots of "tss" (I dunno if there's an official term for "tss" haha).
Also, the V6's are best to be avoided when watching movies... especially ones with guns, shattering glass, screams, etc... I learned that last night.
