According to this Associated Press article, Hummer has been trying to find an indie rock song to use in a commercial. Unfortunately for Hummer, when asked, most indie rock bands respond, "We'll do anything BUT Hummer."
"The Thermals, a rambunctious rock band from Portland, Ore., were en route between gigs last year when they got a phone call from their label, Sub Pop. Hummer wanted to pay them $50,000 for the right to use their song "It's Trivia" in a commercial. "We thought about it for about 15 seconds, maybe," lead singer Hutch Harris said.
They said no...
"It had to be the worst product you could give a song to," Harris said. "It was a really easy decision. How could we go on after soundtracking Hummer? It's just so evil."
