Jay Z's second annual Made in America Fest hit Philadelphia over Labor Day weekend, uniting acts as disaparte as headliners Beyonce and Nine Inch Nails plus a host of others, like R&B smoothy Miguel, rapper 2 Chainz, Parisian pop-rock outfit Phoenix and stoner-rock vets Queens of the Stone Age. It was meant to be a musical melting pot, all gathered in the name of Hova and, of course, corporate sponsorship from Budweiser. But it didn't go down so smooth for QOTSA frontdude Josh Homme, who had serious issues with security, marketing and, finally, Jay Z himself. 

In an interview with CBC Radio 2's "Strombo Show," Homme had a few surprisingly brash words for Hov. "That guy's a kook, you know," Homme said of the iconic rapper. "He has his security frisking the bands on the way in." 

Homme reportedly threatened to cancel QOTSA's set when securtiy insisted on looking through his bag. "No one's ever done that," he said of his band's many previous festival experiences. Then he addressed Jay directly: "You shouldn't frisk my guys, you should f-ck off."

Homme added that Jay gave QOTSA a bottle of champagne and requested that they snap a picture with it. "I was like, 'That's not a gift -- that's a marketing tool.' I destroyed it, 'cause I thought it was rude overall." Later Homme makes a thumping noise, then says, "This is me breaking Jay Z's gifts." 

"People never say anything bad about Jay Z, do they?" he added.
