I suspect that the whole concept of genres was dreamed up as a means of excluding music someone doesn't want to hear!
What is "Americana"? Is it country music without the right wing, religious, drinking cliches? How is it different from folk? Wait, isn't bluegrass folk music?
"I don't like Jazz" -- "OK, listen to this" -- "Oh, I like THAT .. it's that other jazz I don't like!".
Same with rap, prog rock.. whatever.
Is it highly polished, with real instruments and a well-trained vocalist singing so we can hear what the words are? Let's call it "easy listening"!
There are certainly musical styles - reggae, samba, rock, etc.. that often describe the beats and rhythms. However, these can cross "genres".
If you are promoting work, it can be whatever genre the audience wants!
