Jonghyun. He seems to be mighty comfortable when it comes to singing (including offstage) and that makes me confident about listening to him doing so.
Hmm...I enjoy slow, moving, beautifully written songs that express one's love for another. So my preferable choice would be "Love's Way".
It portrays the experiences of being together in a way of learning from your mistakes and creating a bigger "love". Filled with intelligent similes and metaphors throughout the tune, this aged yet magnificently written work touches my heart every time I hear it.
And guess what? I listen to it just about every night to help me go to sleep.
Thanks for the great question. (:
I would pick Taemin coz his voice has been gradually improving and it makes me want to hear his voice more n more <3
I'd like him to sing Honesty coz it's a very special song not just for me but to everyone here :D
