Most definitely better. I tweaked around with the mp3 a little. Pulled it down some in the 250hz range and bumped a little at 1khz and 8 kHz and everything opened right up. They were small adjustments, so I think you are real close.
Hey, I've listened to a few of the mixes of this over the last week, but never got chance to comment. Mix four sounds damn good to me and a definite improvement on the earlier ones - nice balance between the many vocal layers and drums sound good.
This is my era of computer games too - never made the transition from 90s atari/amiga games into the new millennium.
