What I truly wished one could do was have a box in the music upload of one's profile, and untick "allow rating". I personally am not at all interested in having people "rate" my music, as that is meaningless to me. I just have my music here to promote it, not to find out what the majority of people rate my songs to be. Imagine a band like Einsturzende Neubauten posting their music on bandamp. Their song would probably be getting and average of 20-30%, but why would it matter, as it's the handful of people who care deeply about that "type" of music, whom you are trying to reach.
