SISTAR Talks Busy Year Since Topping Inaugural K-Pop Hot 100 Chart

It was an unforgettable moment for Sistar: on August 26th, 2011, the day Billboard's Korea K-Pop Top 100 Chart launched, Sistar's single, "So Cool", emerged as the inaugural No. 1. The girls were celebrated in various publications and of course on Billboard Korea's website. In the two years since they debuted on the scene, they have achieved a string of awards, honors, chart toppers and other career milestones, including headlining the Billboard K-pop Masters at the renowned MGM Grand in Las Vegas, any group would kill for.

Sistar is still one of K-pop's hottest acts and now the sexy quartet tops the K-Pop Hot 100 this week with their latest single "Alone" bumping the two-week reigning Busker Busker to No. 2. The song was composed by Brave Brothers (the masterminds behind "So Cool"). "Alone" is a dreamy mash of infectious disco beats with funky piano and guitar stylings. Their seductive voices speak about the pain of a broken heart. In "Alone," it appears that Sistar has broken away from their signature power dance sound and rediscovered themselves as sexy femme fatales. The music video (shot in Las Vegas) is also a dazzler, as the girls perform alluring choreography in body-hugging dresses playing up their feminine charm and shapely legs.

Nell released their long-awaited fifth album, "Slip Away" on April 10th. This is the group's first studio album in nearly four years. The title track on the album, "The Day Before," jumped to the No. 4 spot (from No. 26) this week. "Slip Away" was produced both in the U.S. and U.K. and is a mellow, piano-driven modern rock track. The accompanying video features actor Song Jae Rim and actor/model Lee Min Ki. Song Jae Rim, as you may recall, rose to stardom for his role on the popular South Korean drama, "The Moon that Embraces the Sun".

The quartet started out as an indie band and shot to fame as soon as they debuted in the major music scene with tunes like "Walking In the Memory" and "Lost My Feeling."

Sexy idol quintet, 4minute (which includes Billboard.com's 21 Under 21 honoree HyunA) proves the excitement regarding their comeback, logging in at No. 3 (up from last week's No. 15) with new single, "Volume Up". The track is a creation of Shinsa-dong Tiger and Rado. It's a tune about how the girls will fight and work hard despite snide comments from critics and the public. The song itself plays along with the saxophone trend both Katy Perry (with "Last Friday Night (T.G.I.F.)") and Lady Gaga ("Edge Of Glory") helped blow up last year. In the must-see music video, the girls display their fierce charisma as vampires amongst dark imagery and sexy dancing accompany the visual.
