The Black Keys could soon bring in a little more gold thanks to a pair of lawsuits.   Reports say Dan Auerbach and Patrick Carney have filed two separate federal complaints against Pizza Hut and Home Depot.  The musicians claim the pizza makers used their song "Gold on the Ceiling" without obtaining the proper rights, while arguing that the hardware retailers did the same with "Lonely Boy."  Both tracks come from last year's album "El Camino," which was co-produced by the duo's fellow complaintiff, Danger Mouse.  The Keys are seeking damages and an immediate end to the airing of the commercials in question.
A spokesperson for Pizza Hut says they are unaware of any issue, but they still plan to investigate the band's claim.  Likewise, Home Depot says they're still reviewing the complaint, adding that they consider respect for intellectual property to be "enormously important."
