Kang Gary appears to have proven one more time, for the record, that sex sells, as the rapper's new single "Shower Later" debuts at number one this week on the Billboard K-pop Hot 100, presumably on the strength of a red hot music video that shatters the genre's international reputation for being tamer than the West.

The video for "Shower Later," which Billboard translates as "Some Occasional Showers," features a collection of hosed down women simulating sex acts in cars and with power tools.

Gary, one half of the popular hip-hop duo Leessang, has two songs in Billboard's K-pop top 10 as a solo artist this week, with his song "Zotto Mola" coming in at number 10.

"Something" by four-member girl group Girl's Day appears to have staying power, jumping three spots, from number five to number two, in its third week on the Billboard K-Pop Hot 100 .

Earlier this month, Billboard's Jeff Benjamin wrote that "Something" "might prove to be the group's hottest moment yet."

"As usual, Girl's Day's strong, elastic vocals are the centerpiece of the production jumping from a soft head-voice delivery to diva growling," Benjamin added.

After debuting last week at number one, K.Will's "Like A Star" dropped to number three on Billboard's K-pop chart.

Written by the successful soundtrack composer Kim Sae Jin, "Like A Star" is yet another chart topping single from the soundtrack for the television drama "You Who Came From The Stars."

Lyn's "My Destiny" currently holding firm at the chart's number four spot for the second week in a row, is also from the "You Who Came From The Stars" soundtrack.

And rounding out the top five is singer Ailee's collaboration with Wheesung, "Singing Got Better," down from the number three position on the chart last week.

The R&B vocalist wrote and produced "Singing Got Better" for Ailee. He also appears in the video.

Although the song was recorded three years ago, its release had been delayed while Wheesung served out his mandatory two years in the South Korean army.
