BS is for conversation not music related. If there's no BS & not one of the other prefixes, I think we assume it's conversation.I know I was agreeing, but I have to make one point that has affected reactions here. If you want to talk, please, say something. If you have a topic you want to talk about don't say, "What do you think about this?" Say, "Here's a bit of what I think, how about you?"
If you don't say something to start with you don't seem to be looking for conversation as much as asking others to perform for you. If that's what you want, the old threads will do perfectly well.
