I know that the answer to the question "Frank Sinatra is an example of what genre of singer?" is in "Artists contributing to this format include mainly soft rock/pop singers such as, Andy Williams, Johnny Mathis, Nana Mouskouri, Celine Dion, Julio Iglesias, Frank Sinatra, Barry Manilow, Engelbert Humperdinck, and Marc Anthony.". Can you tell me what it is?
