This is great. Still, while I do understand why you added flamenco and Rachmaninoff, technically neither all flamenco music, nor every piece by Rachmaninoff can't be a warhorse in itself. It has to be specific flamenco music that has been used a lot or a specific Rachmaninoff piece, also used a lot, as there is a lot of flamenco music and a lot of pieces that Rachmaninoff composed. Theoretically, someone could choose a not so well known flamenco piece that has not been used in figure skating before, or a previously unused or little used Rachmaninoff piece. And then we would not be able to truly say that it's a warhorse, as flamenco music is just one of the music genres, just like pop, rock, blues, jazz or classical music (in a wider sense), and not all Rachmaninoff is the same. But, again, I understand why you did what you did here. A lot of skaters use flamenco music, and, I suppose, to many people it does sound all the same or at least very similar, and usually it makes for programs that are very similar in style + often those skaters/ their choreographers/coaches choose several flamenco pieces for their program, so it's difficult to say which particular piece is the main flamenco warhorse. As for Rachmaninoff, unfortunately there are just a couple of pieces that skaters usually use, but to name "all" two or three of them would take up too space.
