I think he's the one with the most beautiful voice... the voice that is "hypnotizable", that could make people in "goes-to-heaven" mode. However, Junsu doesn't only have the soothing voice... coz his voice could also be heard so sexy or powerful as well. It's just that I can't resist it when he sings ballads...coz it's just so indescribable beautiful!
