Personally I think you can't ignore period works like these if you're talking about a late nineteenth century source. Anachronistic soundtracks bother me a great deal--I run into this all the time when I'm putting together fanmixes for my own fic, It's fun to try to root figures more firmly in their own time: what would they be listening to? What would they have grown up on? What would sound new and novel to them? You have some good suggestions here.
