OK, so maybe this isn't brilliant, but whatever. I was thinking about it, and zero-bombers are really, really annoying around the audio portal, right? So, what if you had to leave a review if you vote zero on a song? That could lead possibly to a bunch of short, spammy reviews everywhere, but those can be marked as abusive and deleted, right? I think that it's a pretty good idea, but I haven't put a whole lot of thought into it, so don't be harsh in explaining anything wrong with it.
