It's definately subtle.. I can usually tell when it raises the volume of something, but I'm not quite so sure if it works for the main thing I need it for - changing the volume BETWEEN songs... example:
really soft song, followed by a really loud song..

The loud song still requires me to turn the volume down manually:(
