Alright:
1)Serj Tankian: Amazing voice and great range. And because he is god.(System of a Down)
2)Mikael Åkerfeldt: Because his clean vocals are amazing and his growls are amazing and terrifying live.(Opeth)
3)Till Lindemann: His voice is just so badass and powerful. Plus how he rolls his R's is just epic.(Rammstein)
4)Marco Hietala: Because his voice is like a a roaring hurricane given form.(Tarot/Nightwish)
5)Dio: Haven't been listining to him that long but he is a pretty amazing singer.
6)James Hetfield: Cause it's James fucking Hetfield.(Metallica)
7)Randy Blyth: His screams and growls are inhuman.(Lamb of God)
8)Nathan Explosion: How can someone death growl and sing that fast?(Dethklok)
9)Daron Malakian: Caus S.O.A.D is the greatest band to ever be formed.
10)Troy Sanders/Brent Hinds/ Brann Dailor: This trio form one of the greatest metal bands going, combined they are powerhouse of contrasting vocals that support each other magnificently. And Troy is the great grandson of cnl. Sanders, the kfc guy. Yeah chicken ftw.(Mastodon)
EDIT: I just remembered. An honourable mention goes to Howard Jones from Killswitch Engage. Though an extremely diverse and badass singer, I felt he didn't quite live up to the other guys here though. But that's my opinion.
