How about letting him learn to make his own music?
drumbit.app/ makes it possible to programme your own beats, for example.
There are free DAWS available online, such as reaper. Add a keyboard (it's easier than drawing each note in individually) and he could do everything. You can rip beats tracks from youtube and import them, then record other loops, add samples, etc, on top.
Or if you've got a mac, Garageband is bundled with it.
It combines music and computers without hundreds of hours of practice or lessons.
The only sport I enjoyed was Hockey (to be able to take my stresses of the day out on the people who had caused them) - or weight training. I have absolutely zero interest in any other sport whatsoever, even though I was a fair to middling 200m runner, could swim and quite frankly, most of the people I went to school with were utter dickheads, so Brownies/Guides and any other complsory group activity was just another few hours of being miserable.
I did like dance, but that wasn't allowed.
I also disliked school music lessons - but I taught myself to play everything else and now make a living from it - by choice.
I was happy watching B movies and drawing cartoons. Anything else would have been met with disinterest - particularly if I was being forced to do 'something' that met somebody else's ideas of what I should do.
