One idea could be to purchase tickets to an electronic/dance music festival or concert that he's interested in attending. Alternatively, you could get him some high-quality headphones, a speaker, or a bluetooth speaker to listen to his favorite music with. Another idea could be to gift him some vinyl records from his favorite electronic/dance artists, or a subscription to a record-of-the-month club that specializes in electronic music. If he's into playing music himself, you could consider getting him a digital DJ controller or some music production software.
Or you can get him a star map with the date when he was born.
