The Top Ten
1Maynard James Keenan - ToolMaynard James Keenan, often referred to by his initials MJK, is an American musician, record producer, winemaker, and actor, best known as the vocalist for Grammy Award-winning progressive metal band Tool.
"Baritenor" is a contrivance, and not a legitimate vocal-range designation. No "baritenor" has both the full richness of a baritone AND the clear, high range of a tenor (falsetto doesn't count). One is either a baritone or a tenor. Willie Nelson is no baritone. His range fits that of a tenor. Bob Seger is a tenor. His lowest notes, while they work for his music, are not within his natural range, much like Robert Plant's falsetto is not within his natural range, though he is a tenor.
2Bob SegerRobert Clark "Bob" Seger is an American singer-songwriter, guitarist and pianist. As a locally successful Detroit-area artist, he performed and recorded as Bob Seger and the Last Heard and Bob Seger System throughout the 1960s.

6Ralf Scheepers - Primal Fear, Gamma RayRalf Scheepers is the vocalist for German heavy metal band Primal Fear. He has a relatively high-pitched tenor-esque singing voice and sometimes uses a shriek reminiscent of Judas Priest's Rob Halford, although it is his baritone lows which give him a near four-octave range in the modal register.
He's even a high-pitched singer with Halford-esque shrieks (Primal Fear - Strike). - Metal_Treasure
