SISTAR19 to be First 'Long Run' Song of the Year?

It seems that SISTAR19 will be the first song of the year to make a long run.

Last month, SISTAR19 released their new song, "Gone not Around Any Longer." Today marks the 18th day in a row that they have been at number 1 on the charts. This is the longest record of this year so far.

SISTAR19 is a unit group of SISTAR and consists of members Hyorin and Bora. 

They have been gaining attention for their unique voices and sexy performances. 

They worked with producers Brave Brothers to create this song as well.

Their different stage performance with see-through chairs also gained much attention.

They also ranked number 1 on Mnet "M! Countdown" and  KBS "Music Bank."
