Ok maybe your words came across more aggressively than you meant

I and others have mentioned artists or posted links to songs to demonstrate the variety and quality of music on the folk scene today - there may be artists others haven't come across so it also serves to bring people's attention to them and explore further. So it does serve some purpose I believe

Your idea of critiquing songs is an interesting one but I would feel a little uncomfortable opening a contemporary song writer's song to public and anonymous criticism. I have written many CD and live reviews in the past for magazines and websites but at least the musicians in question knew who I was (to my cost occasionally!) Also your idea of what makes a great song is not likely to be the same as mine!
