To take the extreme posotion, up till about fifty years ago accents varied so much from village to village that it was easy to pinpoint where somone was brought up. So if you're really worried about your accent, you should stick to (traditional style) music written a couple of miles from your birthplace.

It's a similar dilemma for those of us with a "classical" musical education. We will never sound like folk musicians, so should we play folk music. It certainly raises eyebrows among the "preciousists".

No, the music you play/sing isn't someone elses, if you love it, it becomes yours, an extension of your own personality. If others don't like it, thats their problem. Just don't (as someone else mentioned) stray into religious areas, unless your sure it's safe!
