Pantera's 1991 track "Walk" is extremely aggressive, while The Marvelettes 1966 track "Don't Mess With Bill" is decidedly less so. The latter is also pretty aptly-named considering they're mashed together by YouTube mashup overlord Bill McClintock, taking the vocals of Phil Anselmo and putting them over the very ill-fitting music of The Marvelettes.
Still, it's a lot of fun.
