So it just makes the sound of the mp3 more balanced or w/e? right? Also it only does it if I choose to do it manually, correct?
I don't know why you keep repeating your question, which has been answered as far back as in the first reply.

If you make foobar scan the Replay Gain values of your files, it will write the Replay gain values (track and album gain) as tags in your files.
IF YOU MAKE IT = YOU "MANUALLY" DO IT.
