The title says it all. I think it would be neat to have an official Future funk (japanese funk) playlist by Spotify. It could go in Anime or Funk. If you really want to go the distance, you could make an entire genre named "Futuristic" You could also add experimental and lofi music in there. Basically anything with futuristic would be a neat addition, actually. Especially since the genre is one of the fastest growing genres right now.
