JYP (Park Jin Young), who is giving many contestants constructive criticism as a judge for "Super Star K", has also criticized singer Kim Bum Soo. JYP made a cameo appearance in Kim Bum Soo's teaser video for his 7th album's title track, "????" ("It Passes By"). Apparently, he warned Kim on the dangers of plateauing, saying, "There's nobody who doesn't know you're a great singer. The problem is that you need something new to break all the expectations." A representative of Kim Bum Soo clarified, "Park Jin Young had enough affection for Bum Soo to give him his title song and take charge of the vocal directing himself. Kim agreed to Park Jin Young's warning and used it in his teaser, because he thought it was an assignment he would have to work on from now on in order to improve himself." "It Passes By" features JYP's ballad style, and is going to be officially released on the 29th. JYP added, "I was absorbed in electronic music for a while, so I'm excited to be working with the sound of instruments and vocals as a focus."
