MASTODON cover ZZ TOP on an otherwise terrible CD

A sign of the "classic rock" sound MASTODON are allegedly headed in? An excuse for an unlikely collaboration between awesome musicians? The selling point of a CD that also features MICHELLE BRANCH and even weaker bands like DISTURBED, THE USED and AVENGED SEVENFOLD? The answer to all three is "Just Got Paid," Mastodon's ZZ TOP cover that features original beardo Texan BILLY GIBBONS ripping away on some filthy blooze guitar. It's not entirely metal, but it does rock, and it's streaming right here.
