K-Pop Hot 100: 2NE1 and T-ara Overthrow SISTAR

T-ara did a re-peat. The vivacious girl group hung on to the top spot on the Billboard K-Pop Hot 100 Chart for a second straight week, with their bubbly single, "Lovey Dovey." The young ladies have, of late, just kept on coming with the big hits. In late November and the first week in December their "Cry Cry" single stayed atop the heap for two straight weeks.

Meanwhile, hip-hop heavyweights Dynamic Duo returned with their double album "Dynamic Duo 6th Digilog 1/2 & 2/2," to commemorate their 10th anniversary. There was more to celebrate as Double D roared back into the music scene after a two-year stint in the military. Their track "Without You," has become an instant sensation, rising to No. 5 on this week's chart, and proved to everyone the boys didn't lose a thing in their hiatus. Their newest hit oozes with the heart-ache of lost love and emptiness.

Debuting at No. 9 are the wonderful Wonder Girls, JYP Entertainment's top girl group, with their latest U.S. single, "The DJ is Mine," adding yet another chart-popping single to their extensive list of hits. This fun, high energy pop track with a dustup beat was created by Cri$tyle, one of the most prolific producers in the industry. The group is known for taking risks, having left Korea at the pinnacle of their career to pursue their American dream. The girls toured with the Jonas Brother and quickly made history by being the first K-Pop group to debut on the Billboard Hot 100 chart. With their upcoming movie and new single, the girls are aiming for another top spot on the Billboard charts.

Also debuting this week, at No. 8, is the five-member boy band MBLAQ with their powerful title track, "Its War". The song is expected to peak higher next week.

Co-ed band, Sunny Hill, took a huge leap this week with its newest digital single, "The Grasshopper Anthem", to close in at No.10 on the K-Pop Hot 100 list. "The Grasshoppers Anthem" was created by the ultimate duo of bangers, composer Lee Min Soo and lyricist Kim Min Ah, the artistic team who also wrote, U's "Good Day", "You and I," among others. The inspiration for the song comes from an Aesop's fable, "An Ant and Grasshopper."
