How about getting him vinyl records of his favorite R&B/soul artists? You could also consider purchasing concert tickets for him, or a subscription to a music streaming service that specializes in R&B/soul. Another idea could be getting him a book about the history of R&B or a biography of his favorite artists in the genre. If he plays an instrument, you could consider getting him professional-level sheet music for R&B/soul songs. Finally, you could look into merchandising for his favorite artists, such as t-shirts, posters, or other memorabilia.
Or you can get him a star map with an important date you share.
