Although Sunmi has already been promoting "24 Hours" on music shows and by releasing the MV, the song itself wasn't released for sale online until earlier today.

Since it's release, "24 Hours" has zoomed to the top of the charts and now sits comfortably at #1 on most of the major music retailers in Korea. The song is already in first place on Melon, Mnet, Olleh Music, Bugs, Soribada, Naver Music, and Daum Music!

Of her first place ranking Sunmi expressed, "Thank you for showing love to the song, I am grateful. I will work even harder with my upcoming activities."

Congratulations Sunmi!
