K-pop Chart Report: 4minute Scores Second No. 1, Lee Michelle Flops With First Single

4minute is one of K-pop's longer running girl groups having been together for five years now, but it's not until this past year that they've started charting No. 1 hits. They first achieved the feat last April with "What's Your Name?," and the girls finally strike gold again this week as their latest single, "Whatcha Doin' Today," debuts at No. 1 on the official Gaon chart.

It was a close race to the top, with only the tiniest difference between 4minute and Lim Chang-Jung's "Ordinary Song," which debuts at No. 2.

2NE1's "Come Back Home" falls to No. 3, while Soyou and JungGigo's mega-hit "Some" slips to No. 5.

Orange Caramel stays strong at No. 6 for a second week in a row, while Busker Busker's two-year-old hit, "Cherry Blossom Ending," continues its rise back up the charts by climbing to No. 10.

AOA's "Miniskirt" is still in the top thirty after two and a half months, this week sitting at No. 28.

Ga-In's new single, "A Tempo," enters at No. 22, while rookie boy band TROY rocket 75 spots to No. 32 with "Green Light."

The most interesting entry on the charts this week belongs to Lee Michelle, who crashes and burns at No. 142 with her debut single, "Without You." Michelle first rose to fame on season 1 of reality TV singing contest, K-pop Star, which landed her a record deal with YG Entertainment. She was supposed to debut in YG's then highly-publicized girl group, SuPearls, but after almost two years of training, the group was disbanded and Michelle was dropped. Considering how much controversy the disbandment caused at the time, you'd think her long-awaited solo debut would've been a big hit. "Without You" has since fallen out of Melon's top 100 and the instiz iChart, so the chances of it climbing any higher next week are slim to none.

Anyway, check out this week's key K-pop hits below!
