What was the B-side of Metallica's 1991 single “Enter Sandman”?

“Stone Cold Crazy” was the B-side of Metallica's 1991 single “Enter Sandman.”

The track is a cover of a song originally recorded by the British rock band Queen. Metallica’s version had already appeared on the 1990 compilation album Rubáiyát: Elektra’s 40th Anniversary, where it was included among performances celebrating the record label’s history.

When “Enter Sandman” was issued as a single, “Stone Cold Crazy” provided a compact, high-energy companion track. The pairing also demonstrated Metallica’s longstanding interest in interpreting earlier hard-rock and heavy-metal songs, a practice the band later explored extensively on Garage Inc.

This B-side is easy to confuse with songs from Metallica’s later covers releases. “Am I Evil?” and “Breadfan,” for example, are associated with other Metallica singles and compilations. The specific B-side paired with “Enter Sandman” was Metallica’s cover of “Stone Cold Crazy.”
