it is a great idea, it is excellent....
i think the person who made the song / recording perhaps could get to award a price existing of forum glory to the best track in his or her opinion (but i think Terry will not approve that
, sorry terry, just joking, last time really, i know we should stop now)
i will not compete, because i know i would completely murder the track with too much reverb etc, but it will certainly be an excercise where we all can learn from others, as we can compare the different mixes and ask how certain specific things were done by the mixer
i especially want to try to understand and learn how people mix vocals....how people get them to fit just right in the mix, and yet keep the lyrics clear
