Ah, the 2000s. Aaron Carter and Jesse McCartney were pretty much every girls crush, MGMT made us all think we were scene, and Eminem made everyone feel like gangsters. Whether you jammed out to these classics at your middle school dance, or in your BFF's basement, these hits are unforgettable.

1. "I Want Candy" by Aaron Carter

To my first crush, I never thought I'd see the day that tickets to your concert were $20.

2. "Say My Name" by Destiny's Child

RIP to the coolest female trio.

3. "What A Girl Wants" by Christina Aguilera

Because every middle school, pre-teen girl needed to know what she was worth.

4. "Oops! I Did It Again" by Britney Spears

Before she went crazy, she was my role model.

5. "Girlfriend" by Avril Levine

The anthem for every girl when her crush fell for the wrong 7th grader.

6. "Milkshake" by Kelis

This one goes out to the parents that said we couldn't listen to this, and the older kids in the back of the bus who said we would never know what this song was about (now I do).

7. "Ignition (Remix)" by R. Kelly

It's the freakin' weekend baby, I'm about to have me some fun.

8. "Gold Digger" by Kanye West

Dear Kanye, thank you for teaching me to get a prenup when I get married.

9. "Bouncing Off The Ceiling" by A*Teens

This song made us all feel invincible, even when we quickly learned we couldn't literally bounce off of the ceiling.

10. "Beautiful Soul" by Jesse McCartney

Even though Jesse fell off the face of the earth, he will always be the most beautiful soul of the 2000s.

11. "Bye Bye Bye" by 'N Sync

Throwback to when Justin Timberlake's hair looked like raw ramen noodles.

12. "Since U Been Gone" by Kelly Clarkson

No, this song didn't premiere in the "Pitch Perfect" audition scene.

13. "Lose Yourself" by Eminem

Rabbit killed it in 8-Mile, and proved to all of us that we can make something of ourselves no matter where we come from.

14. "In Da Club" by 50 Cent

We weren't old enough to be "in da club." We weren't old enough to sip Bacardi like it was our birthday. But we still felt like the coolest kids ever when it actually was our birthday and we could play this song.

15. "Kids" by MGMT

I remember kids thinking that if you listened to this song, you were in the beginning stages of turning scene. After watching this video in seventh grade, I can see why.

16. "Poker Face" by Lady GaGa

Taking it back to when GaGa first went big, this song was on the radio about 30 times a day. Since then, she's taught us all to let our freak flags fly.

17. "Absolutely (Story of a Girl)" by Nine Days

This one hit wonder remains on my playlist to this day.

18. "Get The Party Started" by P!nk

Yes, here name has an exclamation point in it. Yes, her name is a color. None of these make her less of a rockstar.

19. "All Star" by Smash Mouth

From the soundtrack of the first "Shrek" movie, this song is so nostalgic.

20. "Yeah!" by Usher

Peace up, A-town down. Go ahead and hit the club with your homies.

These are just a few of the most memorable songs from the 2000s. So go ahead and play these on your Hit Clips, or your boom box, because these songs will never get old.
