Not remotely pleasant.
The instruments you are using are... out of tune and in the high and obnoxious register.
The attack and decay on a lot of your leads makes them seem out of time.
This is kind of a train wreck from a mastering perspective.
1. You are clearly missing the point of a 16bit remix and are rating a song badly based on the fact that it doesn't fit your personal tastes. Why do this to me?
2. There is no attack or decay in any part of this song.
