Yes and no Bruce. For the sake of a shorter thread title the "What is a good song and why?" is quite adequate. I think what we tend to talk about here is trying to identify the characteristics which we think our favourites have in common. I believe you are an English teacher, so you no doubt are used to trying to get students to say or write a little more precisely. "I really like it" is an honest answer, but it falls short of being a well thought out critical response. I like the seven songs which I know of your list, but if that is all I can add to a conversation, it is going to be a pretty dull discussion!
