You have the power to pick which song Wonder Girls covers!

Wonder Girls, the K-Pop sensations who graced our 21 under 21 list of music's hottest minors last fall, are bringing their effervescent vocals and energy to the Billboard studios. They'll be here to record a Mashup Mondays cover that will be posted at Billboard.com on August 1.
