So it turns out that the Grammy-nominating committee isn't the only one who struggles to identify metal bands. The Simpsons recently acknowledged its mistaken identification of heavy metal band Judas Priest on a recent episode.

"There's only one surefire way to get fugitives out of a foreign building," said an FBI agent as Judas Priest played in an attempt to scare Homer out of the Swedish embassy. "Blasting death metal!"

Although the following quote from a Swedish diplomat was fairly accurate and hilarious (Swedes love death metal...it reminds us of death"), the classification of Judas Priest as death metal couldn't be farther from accurate. Priest represents heavy metal, a genre known for its beefy riffs and edgy lyrical content, but not the blast beats and death growls of more hardcore death metal.

For example...heavy metal:

And death metal, as presented in this staff writer's no. 14 favorite track of 2013:

The real Judas Priest made a cameo during the episode, playing a comical version of their own "Breaking The Law." Metal fans were quick to raise their voices in ire regarding the misidentification, and the show responded by opening the credits with Bart writing "Judas Priest is not death metal" as part of his detention.

The plot point was probably based on the U.S. military's use of rock music to get Panamanian dictator Manuel Noriega to leave his hideout in the Catholic embassy during 1989. That plan involved bands such as the Guns 'n' Roses (and possibly Judas Priest), but no actual death metal.
