Hello, 
I am the arranger of this piece.  I appreciate the reviews so far.  Criticism is the only way I can grow.  However, I wish you could all listen to the original WAV of this.  It's so much warmer and full sounding.  The hi-hat doesn't sound so harsh, the bass is more defined, etc.  I encoded this into MP3 with various programs.  MusicMatch, Cakewalk 9.0, SoundForge, Audiocatalyst...all of them gave me the same file that's on Remix OC. 
I used OGG and it sounded much more like my original WAV.  WMA had mixed results too, but still sounded better than the MP3.  Even encoding in a High VBR bitrate in MP3 didn't solve the problem. 
Anyway, thanks for the reviews.  I will eventually make more and hopefully better arrangements.
