I agree with Jim / Howard on this. We do need words to mean things otherwise we end up with NuSpeak which fails to communicate, or indeed educate.

I *wanted* to learn about traditional folk specifically - not just generally discuss whatever music happens to moves me - when I first came to this forum, and I was able to do so because there are people who know all about traditional folk here and they were happy to help me. If I wanted to generally discuss music that moves me, I'd have gone down the pub ;-)
