"One" by Metallica.

"My Name is Jonas" - Weezer

Think of it: "MAAAAAAAAAAAAAAAH NAAAAAAAAAAAAAAAAAAME IS JONAAAAAAAAAAAAAAAS!" It would rule.

NIN's "Closer".

Scatman

Madama Butterfly by Giacomo Puccini. Oh wait, that's an opera that would make a great rock song.

anything by the Flaming Lips, as proven by Ben Folds.

I think the entire Bat Out Of Hell album would make an awesome opera.

Richard Cheese did a lounge cover of Closer that was just submlime.

"Regulate," by Warren G and Nate Dogg

HAHAHAHAHA "Regulate." HAHAHAHAHA

That is awesome.

I would like Grease redone as classical Opera.
