Disturbed‘s sixth studio album, Immortalized, was officially certified gold on Friday (September 23rd) by the RIAA (Recording Industry Association of America) for sales of more than 500,000 copies. The certification includes on-demand audio streams and digital copies in its tally as of seven months ago. The disc was released in August 2015 and became Disturbed’s fifth straight album to enter the Billboard 200 chart at Number One — a feat shared only with Metallica and Dave Matthews Band.
