Rob Zombie's latest album, The Lunar Injection Kool Aid Conspiracy Theory, is the first in his career to land at No. 1 on Billboard's Top Album Sales Chart, which strictly tabulates physical sales only, also referred to as "traditional album sales." The record debuted at No. 9 on the Billboard 200 as well.
Today, many top artists in any genre experience significant popularity through streaming, but hard rock and heavy metal was faired comparatively well in the physical sales realm, opposed to their more mainstream contemporaries, whose numbers are driven in larger part by digital streaming equivalent measurements.
