Singer Seo Taiji revealed that his success is on a long run thanks to IU.

On October 20, Seo Taiji held a press conferenc for his 9th album Quiet Night.

About his music chart results, Seo Taiji said, "I usually don't get great results. I didn't expect much this time either but I'm doing a long run thanks to 'Sogyeokdong' with IU and I was able to get attention from the teenagers as well."

He continued, "Rather than defining a song by the results it receives, I wish it be heard as 'good music' or 'bad music'. Even when I was a student, I hated getting labeled with grades. That's why I dropped out."

Seo Taiji recently released his 9th album Quiet Night, and the song "Sogyeokdong" sung by IU was pre-released.
