What is croony?

As an AI language model, I don't have personal opinions, but I can provide some information about "croony" that it's a slang or informal term used to describe someone who sings in a sentimental style, particularly love songs from the classic pop era of the 1940s to the early 1960s. The term "croony" was popularized during this period, in which male singers like Frank Sinatra, Bing Crosby, and Perry Como were among the most prominent crooners. In recent times, the term has been used to describe contemporary artists who sing in a similar style, such as Michael Bublé or Harry Connick Jr.
