I do want to add both in the future, but it'd be dependent on having the finances to do so. I've experimented with animations and I'm not great at them, plus they're exceptionally time-consuming to both set up and render, so I'd have to commission someone else to make them.
Music I'd want to get someone to score the whole game, to keep the sound consistent and not just use random tracks leased from the usual places a lot of AVNs use (especially because these places fairly regularly change the terms and conditions of their licenses to prohibit use in NSFW media). A lot of other devs have had trouble with music licensing before, and I'd want to avoid that completely by just working with a person or people for all the music.
So, short answer, yes, I would love to add both animation and music, but only if it's good. And to get good animations and music, for me, means spending probably quite a considerable amount of money for it, and as things stand it's not a viable thing to do quite yet, unfortunately.
