In Jon Lee Anderson's "The Lion's Grave: Dispatches from Afghanistan" he describes an encounter with a man who ended up with several of Mullah Omar's Land Cruisers after he fled into the mountains. He opened up a center console and took out a bunch of secular music cds, and then claimed that they had been in the car when he got them. Apparently, despite beating, torturing and imprisoning people for the high crime of listening to music, Mullah Omar himself liked to kick back with some tunes every now and then.
