He is strong.

Busker Busker Jang Beom Jun is taking over the online music charts as a solo artist, and people now wonder who will be able to stop him.

His title song, "Difficult Woman" has taken first place on eight to nine music charts, and it seems only a strong artist will beat him.

Ailee and Swings seem to be next in line. Ailee's strong vocals and Swings' rap are hoping to be a perfect collaboration.

Also, Bumkey and Wheesung are working together for a duet releasing on August 25 as well.

On August 26, SISTAR will release their special album to continue the success of their recent album, "TOUCH MY BODY." Their photoshoot from Saipan for the special album is already getting the hopes up for their fans.
