The rapper-singer duo '2000 won' received praise for their creative performance on 'K-Pop Star 2'.

Comprised of Kim Il Do and Kim Hyo Bin, the duo got their name when they held their first street performance in middle school and earned 2,000 won (approximately $2 USD).

Performing J.Y. Park's "I Already Have A Woman", the duo added their own rapping parts and lyrics to make it uniquely their own,  coming together at the end to 'converse' with each other in raps and rhythm.

The judges had nothing but praise for their performance. "Sometimes when I do this program, I attack J.Y. Park," Yang Hyun Suk said. "Honestly, I prefer this version over J.Y. Park's. I realized that he can really write songs well. If I can make another diss, I often think about what would happen if he gave up being a singer and focused on writing music instead."

"You didn't just show us a fun stage," he went on to say. "This team has skill."

J.Y. Park added to the praise, saying, "When the music started, I forgot that it was my song and enjoyed the performance."
