During the first four weeks of ABDC, it felt like we saw more of the crews' personal dance styles than in any other season. But change is comin'. The first true challenge heads our way this week, as the crews will have to emulate popular music videos from the past decade. Here's what's been thrown at them, in no particular order:

SALTARE - Metro Station "Shake It"
JUNGLE BOOGIE - Shakira ft. Lil Wayne "Give It Up To Me"
BLUEPRINT CRU - Omarion ft. Gucci Mane "I Get It In"
HYPE 5-0 - Britney Spears "3"
HEAVY IMPACT - Colby O'Donis "What You Got"
ROYAL FLUSH - Cascada "Evacuate The Dance Floor"
POREOTIX - Rihanna ft. Jay-Z "Umbrella"
STATIC NOYZE - Little Boots "New In Town"
