Thank you for that explanation. It helps a lot. I really don't care about track gain because during the album rock era there were tracks that were considerably softer and quieter than any other track on the LP and it was by design and applying track gain to them absolutely ruins them so I am good with album gain.
I also love Musicolet and have been using it for 7 years or so and I have lots of favorites etc. so switching for a feature I really don't care about would be foolish.
Now if emby would just support RG but they are so far behind the curve on many things I won't hold my breath.
