1. "I Gotta Feeling" — The Black Eyed Peas
2. "Best I Ever Had" — Drake
Circa the era when people were still like, "Hey, did you know that guy was on Degrassi?"
3. "You Belong With Me" — Taylor Swift
The signs-in-the-window gag is still an internet gift that keeps on giving.
4. "Fire Burning" — Sean Kingston
Catchy, to be sure, but did Kingston consider how irresponsible it was to encourage people to dial 911 in non-emergencies?
5. "Lovegame" — Lady Gaga
I still have no idea what half the lyrics are talking about to this day, but it's hard not to love Gaga in this iteration.
6. "Umbrella" — Rihanna feat. Jay-Z
How did this not result in outerwear sponsorships for young RiRi?
7. "Pocketful Of Sunshine" — Natasha Bedingfield
A seasonally-appropriate choice, made even more famous thanks to the Emma Stone film Easy A.
8. "Buy U A Drank (Shawty Snappin')" — T-Pain Feat. Yung Joc
Included because there's almost a 100% chance that some guy in cargo shorts sang this to you at a party 10 years ago.
9. "Hips Don't Lie" — Shakira
This is another song where I have no idea what's going on lyrically, but I still love nonetheless.
10. "Crazy" — Gnarls Barkley
The commercial peak of Cee Lo Green and Danger Mouse's musical collab.
11. "Over My Head (Cable Car)" — The Fray
This song was the saddest, catchiest song that summer.
12. "Snap Yo Fingers" — Lil Jon Feat. E-40 & Sean Paul Of The YoungBloodZ
Very into any song with hand motions.
13. "Hollaback Girl" — Gwen Stefani
Circa the era when Gwen couldn't seem to go anywhere without her costumed backup dancers.
14. "Lose Control" — Missy Elliott Feat. Ciara & Fat Man Scoop
I have no idea who this Fat Man Scoop character is, but I'd like to shake his hand.
15. "Confessions Part II" — Usher
A contender for song of the decade, IMHO.
16. "The Reason" — Hoobastank
Too bad this band hasn't stuck around. I miss hearing the name.
17. "Lean Back" — Terror Squad
Again, my affinity for song choreography rightfully places "Lean Back" on this list and I don't feel the need to explain myself further, but I still sort of feel weird about it.
18. "Dip It Low" — Christina Milian
I'm hoping Milian has another "Dip It Low" on her hands that'll be released one of these days.
19. "Crazy In Love" — Beyonce Feat. Jay-Z
Truly an icon, this one.
20. "It's Gonna Be Me" — 'N Sync
To be revived every year come April 30.
21. "Try Again" — Aaliyah
22. "Jumpin', Jumpin'" — Destiny's Child
Almost enough to break out your pleather halter top.
23. "Absolutely (Story Of A Girl)" — Nine Days
This is still the saddest song to me ever, and even though I know Adele and Sam Smith exist now and that shouldn't be the case, it is.
24. "Drops Of Jupiter (Tell Me)" — Train
But tell me: what does this mean?!
25. "Hot In Herre" — Nelly
Get out your Band-Aids. The king of the south means business.
26. "Complicated" — Avril Lavigne
...Or, alternatively, your tank top-and-tie ensemble.
27. "Without Me" — Eminem
Note the phone used to call Dr. Dre.
28. "Dilemma" — Nelly Feat. Kelly Rowland
...Same with the Excel document Kelly used to text Nelly.
29. "Foolish" — Ashanti
Awww, remember Ashanti?
30. "The Middle" — Jimmy Eat World
This to me feels sort of timeless. Maybe I'm just a hopeless millennial.
31. "A Thousand Miles" — Vanessa Carlton
This song was classic.
32. "Get Busy" — Sean Paul
This is what I hear when I hear this song: Shake. That. Thing. Miss. [Inaudible].
Mid To Late 1990s:
33. "Genie In A Bottle" — Christina Aguilera
Isn't it weird to think that there was a time when Britney and Christina were rivals?
34. "The Boy Is Mine" — Brandy & Monica
Love everything about this music video, including but not limited to the unexpected Jerry Springer appearance on Brandy's TV.
35. "Macarena (Bayside Boys Mix)" — Los Del Rio
So how did this song work? Did people just do their homework while listening to this song or was it always reserved for sporting events?
36. "Waterfalls" — TLC
Even Scream Queens knows what's up.
37. "Don't Turn Around" — Ace Of Base
Mostly because this reminds me of the summer I spent listening to AOB on repeat in college.
38. "MMMBop" — Hanson
Serious inquiry: How many times do you think the Hanson brothers have gotten asked to define the word "mmmbop"?
39. "Baby Got Back" — Sir Mix-A-Lot
Another very serious inquiry: Do you think Sir Mix-A-Lot sent Nicki Minaj flowers after her sample in "Anaconda"?
Now that there's no longer a need for mix tapes, what will our kids will do when they want to give someone a collection of music? Send it via hologram? Listening to these great songs inspires so many questions.
