2. Paul Stanley - the often neglected KISS frontman was, in his prime, second to only Mercury. A fact that is sadly ignored by so many critics. The fact that he was once hired as the Phantom of the Opera says something about his quality and versatility. Stanley between ca 1980-2005 is just pure awesomeness.
5. Ronnie James Dio - Dio is to metal what Plant is to hard rock, the perfect model for the genre. Power, control, range and a distinct sound made Dio a heavy metal God.
6. Klaus Meine - Meine is often overlooked even though he has one of the most recognizable voices in the world. He sings with ease and has a great tone that fits in many genres.
7. Steve Perry - a great sounding voice with an instantly recognizable sound. Great range and a perfect control makes Perry a great singer both live and in the studio.
8. Roger Daltrey - maybe not the most perfect singer technically, but with power and energy he is a huge part of The Who's sound both live and in the studio.
10. Steven Tyler - Tyler basically IS Aerosmith with his familiar voice and enormous charisma. Great range and can sing both hard rock and soft ballads to perfection.
