A couple people mentioned Mike Patton, who I also think is pretty awesome; great voice. He can do a lot with it. He is not my favorite, though.

When it comes down to it, my favorite single musical artist is probably Danny Elfman, the composer of such famous scores as the one to the Tim Burton Batman movie, and the front man to the band Oingo Boingo. He has a good voice, too; he sang Jack Skellington's parts in "A Nightmare Before Christmas," and some of his singing work in Oingo Boingo is very impressive, like the end of "Goodbye, Goodbye." Even if he has expressed anti-christian sentiments in his music (the song "Insanity" in particular) the music is still cool, so I can forgive him for that.

Runners up would be: Billy Corgan of the Smashing Pumpkins; James Dewees of Reggie and the Full Effect, The Get Up Kids, etc.; either of the Johns of They Might Be Giants; and Reese Roper of Five Iron Frenzy and Brave Saint Saturn. Anyhoo...
