The early 2000s were are great time period for music. Justin Bieber was not yet a part of the music industry, alternative music was what you heard on the radio, and your favorite bands were still together and touring. Artists like Avril Lavigne, Simple Plan, and Panic! At the Disco dominated the top charts—what a time to be alive. Here are 10 songs from the early 2000s that we'll never forget!

1. "Dirty Little Secret" by the All-American Rejects

"Who has to know?" This song encouraged us all to keep our own "dirty little secret." These catchy lyrics made it impossible not to sing along.

2. "Ocean Avenue" by Yellowcard

The nostalgia in this song thrilled us. "If I could find you now, things would get better" was one of our favorite lines. This sentimental story was one we simply couldn't resist.

3. "Mr. Brightside" by the Killers

"It was only a kiss, it was only a kiss!" We all felt for the man who watched the woman he loved "calling a cab" to be with someone else.

4. "I Write Sins Not Tragedies" by Panic! At the Disco

Brendon Urie sings quickly, as if gossiping, about a wedding gone wrong. "Haven't you people ever heard of closing the....door?!" he shouts at the cheating soon-to-be wife and her lover. The pairing of the extravagant, circus-like costumes within the music video and Brendon's vocals was just too good.

5. "My Own Worst Enemy" by Lit

"Can we forget about the things I said when I was drunk?" Lit was the jerk that everyone loved, the annoying drunk guy who had fought with his girlfriend last night, and he couldn't even remember why. The chaos of this song drew us in, and we loved every minute of it.

6. "Sugar, We're Goin Down" by Fall Out Boy

This song was the one we all sang along to, but never actually knew the right words... "A loaded god-complex, cock it and pull it." So THAT'S what he was saying!?

7. "I'm Just a Kid" by Simple Plan

What's more relatable than complaining about your childhood? "I'm just a kid, and life is a nightmare!" We can all recall feeling this way at some point during our adolescence.

8. "Girlfriend" by Avril Lavigne

"Hey, hey! You, you! I could be your girlfriend!" This song embodied the typical unattainable high school crush we've all had.

9. "1985" by Bowling For Soup

"Bruce Springsteen, Madonna, way before Nirvana! There was U2 and Blondie and music still on MTV!" This band of punk rock dads sang of a woman, Debbie's, nostalgia for the year 1985. Even though we weren't alive then, we still loved to sing about it!

10. "I Miss You" by Blink-182

Blink-182 knew they had us when they referenced Tim Burton's "The Nightmare Before Christmas" with lines like "We'll have Halloween on Christmas" and "We can live like Jack and Sally if we want."
