"Piece of Me" vs. "Hold It Against Me"
"Piece" enters the competition after receiving a by in Round One for being Britney's only video to receive the top prize at the MTV Video Music Awards. In the Video of The Year-winning clip, Spears addresses the mania that surrounded her private life at the time of the song's release. It goes up against the tech-heavy video for "Hold It Against Me," the lead single from Spears' most recent album, Femme Fatale. On her "Hold It Against Me" video, she worked with a huge name in the video game, Jonas Akerlund. Akerlund has worked with some of pop's biggest names, from Madonna ("Ray of Light") and Christina Aguilera ("Beautiful) to Pink ("Sober") and his most recent muse, Lady Gaga ("Paparazzi," "Telephone"). Can her VMA-winner take down her all-star recent hit? That's for you to decide.
"(You Drive Me) Crazy" vs. "Me Against the Music"
"Me Against the Music" handed "I Love Rock 'n' Roll" its backside in Round One, joining "Toxic" as one of the clips to defeat its competition with over 80 percent of the vote. The elaborate clip for "Music" throws Britney into the ring (or more accurately, the maze) with her idol, Madonna. When these two came together for this song, it was a pop culture event – it was the moment when the Princess and the Queen came together to make some magic. How will it stack up against one of Britney's early fan favorites, "(You Drive Me) Crazy." Only time will tell.
"Toxic" vs. "Circus"
Two of Miz Spears' most elaborate videos go head-to-head here as "Toxic" takes on "Circus" in Round Two. Both videos are, of course, among Spears' most beloved and neither faced a particularly formidable foe in Round One – "Toxic" easily handed "Radar" its backside in a landslide victory, while the only real competition "Circus" faced form "I'm Not A Girl, Not Yet a Woman" came from sentimental longtime fans.
"Womanizer" vs. "I'm A Slave 4 U"
This is one exciting face-off! In one corner is the ultimate comeback video, "Womanizer," which our girl used as a forum to show off her buff bod and return to musical form after a few tough years. Like its sister clip "Toxic," it was a big, elaborate story-driven spectacle. In the other corner is one of Spears' most iconic clips, "I'm a Slave 4 U." In Francis Lawrence's legendary clip, Spears sweats it with her hot and heavy dance crew in a futuristic urban setting. The ultra sexy video was a major change from the more family-friendly clips that dominated Spears' early career. Which hot and heavy vid will rule Round Two? Vote below and make your voice heard.
Second round voting continues through Sunday night (Nov. 27) at midnight. Vote now and vote often! The videos you voted to move on to Round Three will be announced first thing Monday (Nov. 28).
