Love this song too.
Listened to Yoseob's too. His tone isn't as nasally as when he sings with Beast. I don't know what's wrong with his voice when he sings with Beast but he sounded normal in his solo. LOL.
Jonghyun is seems like a big IU fanboy. I think he wrote her a little note afterwards. LOL. But I think she's sooooo overrated. Her performance was good but she does this really annoying thing at the end of her notes where she just trails off instead of holding them out so the notes just end up sounding weak.
Man they had to sing so much for that show. Hyorin had to sing 5 songs for one recording.
