Although he hasn't officially debuted yet, Kang Seung Yoon has been receiving explosive attention after his disqualification in Mnet's Superstar K2. His cover of Yoon Jong Shin's (one of the judges for the show) "By Instinct" has been gradually climbing up on various music charts since his disqualification. However, he was recently ranked number one in nearly all the music charts including Mnet, Monkey3, Melon, Bugs, Soribada, and Cyworld, which is basically considered an all-kill. He beat out some impressive artists including 2PM, Psy, Ga-in, Supreme Team, and JYJ. He's not an idol, nor a veteran, and technically, not even a professional singer yet. Despite this, having achieved an all-kill is definitely something impressive for any artist, but this is pretty remarkable. Check out the cover below.
