I think with anything, not just music. Some people take the time really take it in whats infront of them, not rule it out because there not use to it or dont understand it. (of course those are perfectly human reasons, there are a ton of things i stay "safe" with.) but at the same time its nice to appreciate those who are a little more open minded. They usually have alot more to say.
Thats just my opinion though, what do you think?
