I agree with Lbietz2001 about Josh Groban. His voice is nearly unbelieveable, especially for someone so young (20, maybe 21 now)...but he's a figure from the 21st Century. My nominees from the 20th Century would include Jose Cura and Carlo Bergonzi for opera; Dean Martin, Harry Connick, Perry Como for pop: Lionel Ritchie and Smokey Robinson for soft rock.
