Ok, I've been redirected here, so now that I'm in the right place, heres the dream.. :D
How about instead of having the rater seperate from the review, you add a category beside the 'Overall' that is out of five, and that is where your rate is shown, so it shows others (or just the author if that is how you want to set it up) what someone rated it, then you can press under 'Was this review helpful?' and the answers you could choose would be 'Yes', 'No', 'Abusive' and 'Bomb'. Yes and no are just opinions, consistantly abusive reviews can result in trouble of course, and a review marked as 'Bomb' by enough users would be nullified, the review would stay, but because that amount given to the song is kept record of, and the experience total of the user at the time could be recorded, so as to be able to completely undo a bomb, and if you have reviewed a song and your review was 'spotted' then it also prevents you from reviewing that song again. Consistant review bombing would result in a suspension of the ability to review. Some examples... (The answer chosen will be in capitols).
Good review:
This was great! Overall: 9 Rate: 4

This was a nearly flawless piece, although it had a few annoying issues,
the sound seemed somewhat distorted and was out of sync in some
places. Nice job anyway, the piano and electric guitar oddly sounded
quite in harmony with eachother, and fitted the beat well. Keep it up!

Was this review helpful? 'YES' 'no 'abusive' 'bomb'
And so that review would stay and it could inform others what you thought of the review, where as a review like this...

And that review after being flagged would automatically be deleted and I would have been prohibited from reviewing this song again, if my giving it a zero dropped its score from a 4 to a 2.30, then when my review gets deleted, it would raise the score up the amount it was dropped, in comparison to the amount of rates it has been given and whatnot, so that might mean that the score is 3.90 when my review gets its final gasp of air, and that might raise the song up to 4.20.
Of course its up to the user to decide whether a review is being abusive, or just bombing, but one should be able to select both in case it turned out to be both.
And so you don't have to wade through a bunch of crappy reviews, you could also set it so that in default it shows the order of reviews chronologically, or you could set it to show reviews starting from the most helpful. It would keep count of the amount of times a review has been marked as helpful and unhelpful, so that you can easily filter through the poor reviews to read the interesting ones.
Also, it wouldn't just take one flagging to delete a review of course, it would take multiple, possibly dependent on the amount of reviews a particular song has in total, so its all dependent on how many people would come through the area, the more traffic, the more people it will take to knock out a bad review, lets say a minimum of 10 flags, and then it goes up to whatever a quarter of the total reviews were, so up to 40 reviews would mean it takes 10 flags, 48 reviews will require 12 flags to knock out a review, and 80 would require 20 flags to knock out a bogus review. Make sense? That would prevent reviews from being knocked off quickly without good reason on songs that have many reviews, one person doesn't see the same as the rest but isn't bombing, then it will take more to clear out that review so as to prevent people from unjustly deleting reviews.
This would likely be a long way off, but it may be something to shoot for. :D Feel free to elaborate!
