Younha was a guest on the May 21 installment of MBC's 'Radio Star', leading to some light comparison between herself and YoonA, who has a similar name. 

On this day, Younha said, "When I said that Girls' Generation's Taeyeon and singer IU sang really well it got misreported as the three of us were in the top three in terms of singing skills."

The mischievous MCs asked, "Then who does Younha think ranks fourth in terms of singing skills?"  She was unable to answer, so Kim Gu Ra bluntly stated, "Then let's just say Younha is better at singing than Girls' Generation's YoonA," making everyone laugh.

Kyuhyun said, "I will acknowledge that, as well."  Yoon Jong Shin joked that it was a formal acknowledgement by SM.
