Which would you rather be? A vocalist or a singer? The definition of a vocalist is "a singer, typically one who regularly performs with a jazz or pop group? And the definition of singer? it is "a person who sings, especially professionally." Not much thought in these definitions, coming from established dictionaries.

I did wonder if that is how the Singer Sewing Machine got its name? Because of the whirring song of the stitching? No - it got its name from Isaac Merritt Singer. In 1891 it launched its first musical advertising campaign: “The sun never sets on a Singer sewing machine at work!” Singer became one of the companies which used "jingle" in their marketing activities for the first time. The song “MERRY SINGER”, composed dedicatedly for Singer, made great contributions to reputation of Singer.
