Have you heard of synesthesia? It is when your sensory system mixes your sensory perceptions together. In other words, you may see things others only hear, or taste things others only see, and so on. I see music. I always have. Of course, I also hear music but I get it in 3D with my own laser light show.
My favorite music to hear and also watch in synesthesia are two pieces by George Gershwin, his wonderful Cuban Overture and his amazing, An American in Paris. Close your eyes, listen, and try to imagine this music in lights.
I complain often about the hard parts of autism, but here is a nice feature.
