Kryptonite Video (MV)

"Kryptonite" is the debut single of American rock band 3 Doors Down. It was originally released as a demo for local play by 97.9 WCPR-FM in Biloxi, Mississippi, then was picked up by several radio stations during November and December 1999 and was officially serviced to radio on January 18, 2000.

The song was written by the band's vocalist and drummer, Brad Arnold, in a mathematics class when he was 15; it was one of the first songs he ever wrote. About the song's meaning, Arnold has said:

"That song seems like it's really just kind of like asking a question. Its question is kind of a strange one. It's not just asking, "If I fall down, will you be there for me?", because it's easy to be there for someone when they're down. But it's not always easy to be there for somebody when they're doing good. And that's the question it's asking. It's like, "If I go crazy, will you still call me Superman?"

It's asking, "If I'm down, will you still be there for me?" but at the same time, "If I'm alive and well, will you be there holding my hand?" That's kind of asking, "If I'm doing good, will you be there for me? Will you not be jealous of me?" That's the basic question that song's asking, and maybe throughout the years of singing that song, I might have come up with more meanings for it than it actually might have originally had."

The song first charted on the US Billboard Mainstream Rock Tracks chart, reaching number one for nine weeks, then topped the Billboard Modern Rock Tracks chart for 11 weeks; it was the 2000s most successful song for both rankings. It also reached number three on the Billboard Hot 100, the band's highest-charting single on the listing.
