I used to be when I was younger. Now I just smile and say, enjoy what you like. I am a Smiths veteran and in the early days would dismiss people for life who would say, the Smiths are depressing arent they?
I always had a wide musical taste and that has grown further. I dont get uptight anymore, but I still laugh at people who dont get it.
I have though, a borderline pathological hatred for Prog Rock, even the name makes me angry. But, I dont mind people who like it now. I pity the fools, but i dont hate them.
Apart from that i dont do the snob thing now. I'm too busy hating other things.
