I’ve had a couple of things sell after being up there, apparently unloved, for months. I think as your overall sales rate improves, it matters less that individual tracks are unsold. Personally if I were a customer rather than a supplier, I’d be looking for things that appealed to me – and would feel glad to find something a bit rare and unknown. So it wouldn’t really bother me if the track I wanted had a low (or zero) sales rate. I hope at least some potential customers feel the same way (though I agree with what was said up-thread: some people do feel “comforted” by the idea that other people have bought and used a track before them). I have plenty of unsold tracks but I won’t be taking them down just yet. You never know.
