Yeah, that's what I'm talking about, the Musical Freestyle.

It makes the sport fun and accessible to non-riders and the general public.
Sort of like how music and costumes make the sport of figure skating fun and accessible to non-skaters and the general public.
Obviously, equestrian events would be "more like real sports" if the horses didn't dance to music and if the riders didn't wear such silly outfits, but that's entertainment. No one would ever watch a figure skating contest if it consisted merely of one contestant after another just running systematically through through their array of jumps and spins wearing an old sweatshirt. (That would be too much like school figures, LOL.)
