Why not do both (or all 3 including music) at the same time while giving yourself 2-3 years to start slowly ramp up your focus on the game dev or music side as you keep on learning while reducing your involvement with the management work?

I'm personally someone attempting to find a balance between my full time job, music & game dev/3d graphics. I don't see the latter two paying off any time soon but I see myself doing them for the rest of my life. The one thing I can say that after attempting to give it a go for 2+ years, a certain type of synergy between the different goals start to emerge. Skills & ideas I gain in one area help me do better in the other two in unexpected ways.

The experience & skills you've gathered from running a company would not go to waste and can be your source of strength. And just starting by dipping your toes is the best way to find whether you'd really enjoy being involved in these areas.
