How about tickets to see one of his favorite R&B/Soul artists in concert? You could also get him some vinyl records of classic R&B/Soul albums or a subscription to a vinyl record club that caters to his music taste. Another great idea could be a personalized playlist of his favorite R&B/Soul songs, featuring songs from all the artists he loves. You could also get him some merch from his favorite R&B/Soul artist or a custom-made T-shirt with his favorite lyrics or album cover.
Or you can get him a star map with the date of your anniversary.
