I was about to start a poll when I thought of this topice, but realised how it would limit people's options. Personally Paul McCartney is mine. He can sing every style convincingly. From blues to pop to hard rock, and even country. I admire others greatly like Frank Sinatra, Justin Timberlake, Neil Tennent (Pet Shop Boys) and Ezra Koenig (Vampire Weekend). Who is yours and why?
