JYJ's Junsu had some high praise for 'Superstar K4' contestant Yoo Seung Woo.

Junsu posted to Twitter on October 13: "Yoo Seung Woo. Someone who doesn't just sing well, but knows very well how to sing. I really like that flexibility. His expressions while singing. For [me], it's been you since the start," revealing who he'll most likely be voting for.

He went on, "Also, Hong Dae Kwang. I really like the way you don't let one word, one sound, one syllable, or one letter get past you and [the way you] sing carefully."

On the October 12th episode of 'Superstar K4', Yoo Seung Woo's performance of "My Son" blew away the judges as well.
