Sung Si-kyung highly praised Cool's Lee Jae-hoon

"People love debating who the number one singer is, don't they?"
"So people often bring up seniors like Im Jae-beum, Hyoshin, Beom-soo, Cho Yong-pil, or Na Hoon-a."
"Usually, in these rankings, vocalists with flashy styles tend to get the credit."
"But in my personal opinion, if I had to pick the five best singers in our country's history,
Lee Jae-hoon from Cool would definitely be one of them..."
"Singing with a powerful, raw style is a skill and a merit that not everyone possesses,"
"But he sings in a way that is sweet, easy to listen to, and effortlessly catchy."
