Rationale: While heavy metal drew influence from hard rock and blues rock of the late 1960s, the genre is generally considered to have emerged in the early 1970s with bands like Black Sabbath, Deep Purple, and Led Zeppelin. It wasn't until these bands released seminal albums in the 1970s that heavy metal became a distinct genre and gained widespread popularity.

Rationale: Heavy metal music emerged and was popularized later, in the late 1960s and early 1970s, not first in the 1960s. Bands like Black Sabbath and Led Zeppelin pioneered and popularized the heavy metal genre starting around that time.
