How about getting her tickets to see her favorite R&B/soul artist? Or, if there are no upcoming concerts, you could make a playlist for her that includes all her favorite R&B/soul songs, as well as some new ones she might like.
If you want to get her something physical, you could consider a vinyl record of an R&B/soul artist she loves, or even some vintage vinyl from her favorite era of R&B/soul music. You could also get her a luxury subscription to a music streaming service, with a handpicked playlist of her favorite R&B/soul tracks.
Another great option would be a custom piece of jewelry that captures the essence of R&B/soul music. You could have a pendant made that resembles a microphone, or a bracelet that features lyrics from her favorite R&B/soul artist.
Lastly, you could consider booking her a weekend getaway to a cozy bed and breakfast in a nearby town, complete with a record player and a collection of R&B/soul vinyls for her to listen to as she relaxes.
Or you can get her a star map with the date of your anniversary.
