As expected, Hyorin's solo single, "One Way Love," has taken the top spot on the Gaon chart in its first week out. The SISTAR superstar dethrones last week's chart-topper, 2NE1's "Missing You," which slips one spot to No. 2. The point difference between the two songs is minimal, proving that 2NE1 are actually showing some real staying power with "Missing You" -- something that their last two singles didn't do.

Anyway, with "One Way Love" topping the charts, SISTAR's total career No. 1s now stands at seven: four as a group, two as soloists, and one as the SISTAR19 subunit.

San E's "Break Up Dinner" climbs two spots to No. 3, while Hyorin's other solo single, "Lonely," debuts at No. 4.

In even better news, VIXX's "Voodoo Doll" enters the charts at No. 7 to become the group's first top ten hit and highest-charting single of their career. Their previous best was "G.R.8.U.," which reached No. 14 back in October. The boys also debut at No. 1 on the album chart with their first full-length album, Voodoo, solidifying their status as one of K-pop's hottest rising stars right now.

A few spots down, Younha's "It's Okay" arrives at No. 9, while miss A's "Hush" slips to No. 11 after two weeks in the top ten.

2AM's new single, "Regret," debuts at No. 18, making it their lowest-charting lead single by a fairly large margin, while Crayon Pop's "Lonely Christmas" enters at No. 35 to become the group's third top forty entry after "Bar Bar Bar" and "Dancing Queen 2.0".
