You know that Islamic Arabs are supposed to be forbidden from painting people and scenery. One of the Saudi guys I interviewed told me thats why their handwriting script is so fancy. It serves the purpose of art among Islamics. Many Arabic Islamic countries do have music, but its the most awful stuff Ive ever heard.
I had a nice and profound (for me) response all thought out and typed up and my computer crashed before I could post it. I would like to stay in this discussion but it's pretty risky business right now. Need to get my computer in the shop and don't want to give it up for even a day ;-) (or spend the money).
