Islamic music influenced bands or songs?

Just as a humorous distraction, be sure to check out hizbollah.org's audio section. I'd recommend you have a case of beer first though (or maybe during -- their 'net connection is sloooooow).
 
uhm, holy wars by Megadeth. Not much to go
on, but the only one I can think of, one of the
coolest traditional thrash metal songs ever.
