One idea could be to get him tickets to see his favorite band or musician perform live. Another idea could be to give him a custom-made playlist of his favorite songs or even create a mixtape for him to listen to during his long car ride or while doing a favorite activity. If he collects vinyl records or CDs, you could get him an album by his favorite artist or a new release from a band he's been wanting to check out. Finally, you could give him a Bluetooth speaker to use at outdoor parties or at home while listening to his favorite music.
Or you can get him a star map with the date when he welcomed you in this world.
