Itunes Library Volume Adjustments not Transferring to Music App

I have a large music libary, with several volume adjustments for different artists and songs (e.g Bass Boost, Loudness etc). This saved on Itunes without a problem, and also onto the Apple Music app. + no issues with any music player apps that sync with apple music.

However, Im using a different music player at the moment, and it requires you to copy the itunes music files (located on my windows PC) onto the new app, through file sharing on Itunes. The volume adjustments are not working though, leading to wild volume differences between songs. Why would that be? And is there anything I can do here?
