"am i right that some followers believe music shouldn't be listened to."
A bit like the members of certain Highland churches here in Scotland then (music and dancing being the work of Satan, leading to sins of the flesh). Whose members oppose Sunday ferry sailings and other secular activities on the Sabbath, who don't celebrate Christmas and abhor the pagan festival with its trees and lights and booze which passes for Christmas in the rest of the UK. There are Christians with some very hardline beliefs up here, but because they no longer put people to death for their non-belief, society tends to regard them as harmless and quaint.
Of course, the vast majority of Muslims I've met do not put people to death either, and in fact are peace-loving, tolerant folk, but we do like a scapegoat, don't we?
I'm sick of the casual Muslim-bashing which goes on - those circular emails with their nonsensical claims about "councils stopping Christmas to appease Muslims", for example. The last one of those which reached my inbox had been posted by a cousin of mine - she's Catholic, and (disturbingly) a teacher in an English Catholic school. I sent her a Snopes link - and asked what was the purpose of her email. I didn't hear back.
