This is: Cannonball Tom's Brain.
Or, at least it was. Tom's brain hated him. It thought he was an idiot, which it was justified in doing. It also felt that the other organs were just not up to snuff. The other organs simply felt that the brain didn't know what it was talking about, and was quite a bit too arrogant - but what could it do? It was greatly surprising to them when the brain figured a way out of Tom. It simply left the spinal chord in charge, and set out to find a new set of organs. One that liked smooth jazz and Rachmaninov.
