since you still have trouble it is in the song file its self and not the tags.
only thing to do is convert to wave either by using the converting tool in mediamonkey.
and take it in to a wav editor and adjust the volume values in the wav editor which would create new ones
and should get rid of the old ones because you more likely won't use the same wav editor.
that would be lots of editing work. how ever if you use a wav editor.
play the songs in mediamonkey with the eq settings the way you want. and use the wav editor program to record off the what you hear mixer you will then have a new wav file recorded of the song with out the replay gain value you can't get rid of. the eq will help in keeping some of the sound quality when you record the new wav in the wav editor, then you can just adjust the volume of the wav while your in the editing program. theres a big tip i put on the wiki for how to do that. but making the new wave will make the song file your file and get rid of any of the stuff the other place put in the file to mess with you.
