Working in TV is so weird. You create things that will probably only be used in one episode of one show. For instance, these monster designs.
I was thinking of this sort of thing while watching the anime Frieren Beyond Journey’s End, a classic in the making with a great score. One episode has people dancing a waltz, and the composer wrote a great little waltz that will probably only ever be used here in this one episode. Admittedly, people will probably be watching this show for years and decades to come, but even so. And perforce the score is only a background detail that many people will never notice to start with. Huh.
