I'm not listening all songs from all idols. this is only a list from some idols that i ever heard. mostly from SM, because all artists from sm are awesome (for me). :D
Who doesn't like kyuhyun's voice? I'm in love with it. His voice is soft, smooth, and makes everyone who listening to it comfortable. And my fave song that kyuhyun sang is this. I think he covered this song, right? I mean, this is a song from another artist. I'm not pretty sure. This is a song for movie soundtrack, but i don't remember the movie title. The song's title is 7 Years of Love. Just listening, and you'll fall in love with kyuhyun's voice.
