My rating system is a rating of 1-5. You need the font "Wingdings" to view my rating system. You should have it; if you don't you'll see "C"s. It is based upon my opinion on how close the midi is to the actual game if it was not a remix/arrangement. It is quality when it is a remix and/or arrangement. This ratings are only my opinion. The way the midi sounds depends greatly on your sound card. The rating is as follows:
If not perfect, very close!
I haven't heard that song yet/haven't heard it enough to make judgement
