What I suggest you do is sit down and make a list of those things he is passionate about other than you. Things such as sports; is he a fan of football? If so what is his favorite team? Who is his favorite player? IF you know the answer to these questions and he does not already have an authentic NFL Jersey this is something he might cherish. If he is a car guy maybe something for his car.
The better you know him the easier it will be. Just take a few minutes and as I said sit down with pen and paper and make a list of those things he is passionate about. Music would qualify if there is something he really wants and has not yet purchased for himself.
