What is the title of Metallica’s Black Album song that interpolates the melody from West Side Story?

“Don’t Tread on Me” is the Metallica Black Album song that interpolates the melody from West Side Story.

The song’s introduction draws on “America,” the song composed by Leonard Bernstein for the musical West Side Story. This connection is most noticeable at the beginning, where the melodic idea is incorporated into Metallica’s heavy arrangement.

“Don’t Tread on Me” appears as the album’s sixth track. It was sent to rock radio after the album’s release but did not receive a commercial single release like “Enter Sandman,” “The Unforgiven,” “Nothing Else Matters,” “Wherever I May Roam,” and “Sad but True.”

The reference is sometimes missed because the song is presented as a Metallica composition rather than a straightforward cover. Interpolation means that a recognizable musical passage is incorporated into a new work; it does not make the entire song a cover of West Side Story.
