In this particular case it doesn’t even matter if Serge fits any definition of jazz since I’m sure many of the artists played on jazz radio would not conform to Francois’ (or wikipidia’s) definition of “jazz.”

Yeah, I guess if you want to redefine a term, you can make mean anything. And if it's a term that was loosely defined to begin with...

I go by criteria that were taught to me by my music teachers. This definition is the most widely accepted one among musicians. In order to be jazz, music has to meet a majority, though not all, of the following:

- Melodies are not played 'straight' but embellished and interpreted
- Much of the performance is improvised (most important)
- At least part of the repertoire is jazz standards
- Pieces feature extensive soloing
- Music has a swing feel
- Stylistic touches (scoops, slides, blue notes etc.) that are typically used by jazz musicians

You can take any one criterion and find Jazz that does not meet it. But if music meets a majority of the criteria, it's pretty fair to call it jazz.

Edith Piaf is a pop singer. Her accompanying music isn't jazz music, her singing is not jazz singing, and she doesn't play within the jazz repertoire. She mostly sings songs written by Charles Aznavour, a French 50s popular music writer/composer.

I think it's an insult to rape & abuse victims everywhere to label any consentual act "rape." Whether you precede it with the qualifier "statutory" or not. When you change the meaning of the word to encompass too much, you rob it of its original meaning. Child abuse is horrible. Rape is horrible. Neither are consentual acts, as Serge Gainsbourg sang about.

But beyond that, singing a song about a sexual fantasy does not mean you enacted that fantasy. There are many, many examples of terrible sexual fantasies in cannonical art, literature, and music, that are just that. Fantasies. There's nothing wrong with it. Any psychologist worth a grain of salt would tell you that taboo fantasies are a healthy exploration that releases what could otherwise turn into an unhealthy obsession. Is the person who dresses in PVC and brandishes a whip in a club on saturday night really a medieval whore with alien sex obsessions? No. It's a fantasy, and it's even more titillating because it's taboo. The corresponding real act is forbidden and wrong, which is why the fantasy has so much power.
