JJ Lin collaborated with Jung Yong Hwa and they ACTUALLY performed live TOGETHER on music bank!! I didn't think there would be a live and the song is sung in both Korean and Chinese. If you don't know who JJ Lin; he is a Chinese singer who mainly works in the Taiwanese entertainment circle. He is a singer songwriter.

The song is called Checkmate. I wonder if they wrote it together, because Yong Hwa is also a songwriter.

There were many songs JJ wrote that I like, although most people think he's not comparable with Jay Chou who is also a genius song writer. I think his voice is so much more expressive than Jay's. I'm a bit excited by JJ is not really a rock singer, so this is interesting.
