Vote 4 on all your tracks. Not five. If you have a rating of 4.76 or 4.32, you're unlikely to be zerovoted, as people who do that lurk around on the front page of the audio catagories.
Other than that, who cares about votes? Anyone who has spent more than a few weeks here realises the best stuff resides half way in, as opposed to the blatent, advertised surface.
