Which '00s Summer Song Should You Rock Out To?

It's time for a serious throwback. Nothing like the sound of some old-school Nelly to make you want to dance. So roll down those windows, turn up the song and belt out any word you know. This song will take you back to 2002 and make you forget it came out more than a decade ago.

Rihanna may still be in the spotlight and on the radio, but it's a 2007 jam that will make you feel like it's truly summer. Hopefully the sun will keep shining and that umbrella (ella, ella, ella) will be able to exist only in the lyrics.

Remember 2006? It was a time when Timbaland was like Pitbull - appearing or producing every major pop track that hit the charts. Promiscuous was no different - so sing along to Nelly Furtado's killer vocals and crank up the bass this summer.

Katy Perry came onto the scene in a big way in 2008 with this killer hit. The one that everyone sang along to but never knew if they were allowed to. But before she had a unique style and crazy-colored hair, she had kissed a girl (and liked it) and gave the world a catchy-as-hell tune.

From the "Yeaaaahhhhhh" at the beginning of the track, people in the summer of 2007 were automatically in dance mode. There was no escaping the beat, and once you heard it, it never left your brain. Relive that earworm experience and just start chanting "Party like a rockstar!" over and over.

Alright, this is the epitome of a summer-throwback jam. Remember 2001? That time when Usher was throwing sultry songs around all over the place? This one was no exception. He gladly seduced everyone over the airwaves...and put a "U" in almost every one of his titles.

Okay maybe you're not looking for a true throwback, but 2010 isn't too bad. Pitbull knows how to create a hit, and this one's no exception. Whether you like this one or the Pitch Perfect version better, go nuts! Just belt out every word (Unless you can't keep up with Pitbull's rapping, of course.).

Sometimes a summer song doesn't have to be the peppiest of tunes to become an anthem. Everything about the 2011 Gotye song screamed "hit," from its almost music-box-esque sound to the soulful lament of a love gone wrong. Don't hesitate to scream out all the words - you know you knew them.
