Somehow, Metallica’s “Enter Sandman” has become very mashable. Youtuber Bill McClintock took the Metallica classic and mashed it up with Huey Lewis and the News’ “Hip to Be Square.” Titled “Hip to Be the Sandman,” the clip takes James Hetfield’s vocals and mixes them with the music from the Huey Lewis and the New song. Strangely…it works! And the video cuts work great too.
