Music to which I write (aka 'music to write to')

I don't always write to music, but when I do...

When I write non-fiction (or fitness books (see what I did there?)) I listen to the kind of stuff that's pretty cliché in the industry (metal, rock, etc.).

When I write fiction, it helps to fit the music to the theme, and it's been romance, lately. ...when I have time to write it, squoze in between my legit projects, of course.
