SISTAR have hung onto the No. 1 spot for a second week with their latest single, "Touch Your Body." The song is still sitting comfortably at No. 1 on the Melon digital music chart, too, so we could potentially see the quartet spend a third week at the top of the Gaon chart. If that happens, then "Touch My Body" will become the longest-running No. 1 in almost two years.

Overall, "Touch My Body" is SISTAR's fifth No. 1 as a full group, and their 11th if you include their subunit, solos, and collaborations. It's this kind of success that's helped them become Korea's second biggest girl group -- after Girls' Generation, of course.

In second place is Block B's "Her," which climbs one spot to No. 2 this week. It's the highest-charting song of Block B's career, and its success is pretty impressive by boy band standards. Male artists generally tend to fare better with physical album sales, while the digital market is dominated by girl groups and OST ballads.

HyunA's racy "Red" debuts at a solid No. 3, matching the position of her signature hit, "Bubble Pop!," but failing to reach the No. 1 and No. 2 peak of both "Ice Cream" and "Change."

INFINITE's flawless "Back" slips two spots to No. 4, followed by Girl's Day's "Darling" at No. 5.

JYJ's new single "Back Seat" debuts at No. 6, while all the songs from their latest album, Just Us, are scattered throughout the rest of the top 100.

Further down, Wonder Girls' Yenny, who now goes by the bizarre and confusing name of HA:TFELT, enters at a respectable No. 16 with her first solo single, "Ain't Nobody." The position pales in comparison to her ex-bandmate Sunmi, but is relatively decent by solo female standards, putting her on par with T-ara's Jiyeon and Hyomin.

The new HIGH4 single with Lim Kim, "A Little Close," enters at No. 29, while Sunny Hill's "Once In Summer" arrives at No. 47 to become their lowest-charting single ever.

Speaking of flops, BESTie's "Hot Baby" debuts at a disappointing No. 53. Although this matches "Thank U Very Much" as their highest-charting single, it's still a let down for the group, who should be doing much better at this point.

Check out this week's key K-pop hits, below.

No. 1. SISTAR - Touch My Body

No. 3. HyunA - Red

No. 4. INFINITE - Back

The Korean entertainment industry has been at a standstill ever since the tragic Sewol ferry disaster, and it's reflected in the official K-pop charts. There's been little movement on the charts for weeks, with virtually all of the previously-scheduled new releases having been pushed back to unspecified dates in the future.

Akdong Musician's "200%" takes back the No. 1 spot after 15&'s "Can't Hide It" dethroned the teen duo last week. IU and HIGH4's "Not Spring, Love, or Cherry Blossoms" moves one place to No. 2, followed by 15& in third place.

A Pink's "Mr. Chu" is back in the top five, climbing two spots to No. 4, while Soyou and Junggigo's "Some" hops three places to No. 12, and Orange Caramel's catchy "Catallena" moves to No. 13.

4minute's "Whatcha Doin' Today" is No. 30, Crayon Pop's "UH-EE!" is No. 31... That's about it. Sorry, but there's just not much to report this week!

Anyway, take a listen to this week's No. 1 below.

After debuting at No. 1 last week with "200%," YG Entertainment's AKMU slips one spot to make way for 15&'s "Can't Hide It," which takes the top spot this week.

Both AKMU and 15& are teen pop duos that got their start on the reality TV singing competition K-pop Star, so it's nice to see thing work out for the pairs as they trade places at the top of the charts.

Rookie boy band HIGH4 and their duet with IU, "Not Spring, Love, or Cherry Blossoms," falls one spot to No. 3 this week, while Sihwan Park's "I Just Loved You" debuts at No. 4.

Trending girl group A Pink are showing a lot of longevity with their current hit "Mr. Chu," which is back up one spot to No. 6 this week, while Orange Caramel's "Catallena" bounces back five spots to No. 14.

Meanwhile, Crayon Pop's "UH-EE!" is at No. 25, while 4minute's former chart-topper "Whatcha Doin' Today?" is at No. 29.
