Since the beginning of the 21st century, pop stars have been creating signature dance routines that have become virulent throughout mainstream culture. Whether these dances have emerged in the hip-hop, pop, R&B or electro genres, they've all become crazes at some point or another throughout the 2000's. We've selected 10 of the most popular dances from the past few years, and we're asking readers to vote for the one they've deemed as their favorite.

In 2000, 'N Sync had all of us stomping our feet and jerking our heads to side as we waved 'Bye Bye Bye.' That same year, Britney Spears broke out of her bubblegum mold with her sexy video for 'Oops! ...I Did It Again,' which also sparked a dance craze thanks to the out-of-this-world choreography in the spacey clip.

Ciara also ignited a dance sensation when she released her '1,2 Step' video in 2004. While she may be one of the best dancers in the game, the moves were simple enough for all of her fans to partake. Two years later, rap outfit Dem Franchise Boyz and solo rapper UNK released their respective singles 'Lean Wit It, Rock Wit It' and 'Walk It Out,' both of which flooded dance floors all over the U.S. And in 2007, Soulja Boy kept the Southern rap dances flowing with his single 'Crank That (Soulja Boy)' and its accompanying choreographed routine.

As the end of the first decade of the 21st century drew near, the dance crazes kept a comin'. Beyonce blew minds all over the world with her 'Single Ladies (Put a Ring on It)' dance, which everyone attempted to recreate, however, few could nail the moves quite like the Ms. Knowles. Shortly after, fellow pop diva Lady Gaga got everyone putting their paws up with her courtesy of her 'Bad Romance' clip, which has a very distinct and very addicting dance routine.

In 2010, the Dougie became the dance to know to how to do, and we all were instructed on how to nail it thanks to Cali Swag District's 'Teach Me How to Dougie.' Finally, in 2011, LMFAO released another beast of a dance craze with 'Party Rock Anthem,' unleashing their shuffle for all to try and replicate.
