While SISTAR's Soyou and Junggigo's duet "Some" is topping major charts, Kim Soo Hyun's "In Front of Your House" ("My Love from the Star" soundtrack) is threatening its position.

Soyou and Junggigo's "Some", released on February 7^th, is still ranked #1 on major charts including Melon, Mnet.com, Olleh Music, and Genie.

"Some" is the result of collaboration between K-Pop's best producers Kim Do Hoon, Min Yeon Jae, and Zanybros in their second project of STARSHIP X.

Kim Soo Hyun challenges this dream team, with "In Front of Your House" instantly claiming the top spot in ten music charts upon release. The song still is ranked #1 on Naver Music, Daum Music, and Cyworld Music.

"In Front of Your House" is a soft ballad containing lyrics that express the tragedy of lovers' parting; Kim Soo Hyun's clear voice complements the simple melody of the song.

Also competing for top spots on music charts are Sung Si Kyung's "Every Moment of You", SISTAR Hyorin's "Hello", Huh Gak's "Tears Fallin' Like Today", and Disney animation soundtrack "Let It Go".
