On the November 10th broadcast of SBS Power FM's 'Cultwo Show', Kyuhyun shared that he was very eager to collaborate with the senior ballad singer. He said, "I sent multiple love calls to Sung Si Kyung this time. He really put in a lot of effort for me. He said he'd rather do it right since we're doing it, and he gave it a lot of thought and sang the chorus."
As for his other title track "Blah Blah", Kyuhyun expressed, "Both Yoon Jong Shin's 'Blah Blah' and Sung Si Kyung's 'Still' had a good response within the agency, and they both got similar reviews. That's why I decided to release two title tracks."
Do you prefer "Blah Blah" or "Still"?
