I let mp3gain analyze PJ Harvey's Rid of me (from Six track demos) and I still have to run for the volume control when I listen to this song. This is a very dynamic track but that is exactly what mp3gain is supposed to handle, isn't it?
My intention was to upload the track to the upload forum but since that is limited to 30 seconds samples and you really need to hear the full track in this case, can I do something else?
I use mp3gain 1.4.6 with -r -o
