In my memory didn't use tags but dsp-processed the songs but I may be wrong.

I said "alter too much", e.g. the case where the loudness of an album becomes irregular. I have replay gain tags because I want to use replay gain. I want a similar loudness throughout my music, and I'm not worried about clipping (I never heard it with my music). So I specifically don't want to use all capabilities. And clipping prevention is not without problems. A whole song might get drastically turned down because of a single spike. That would be hugely unpleasant for me. > >> >> c) People (including me) may prefer to risk some slight clipping over >> unequal loudness throughout albums, especially since it comes with a >> battery life cost.

Most defaults are a result of personal preference (most often the personal preference of the majority). And it's my personal preference to keep the default at off. I would think the guy in the forum is in a minority. Sure, we don't have numbers but I follow the reasoning of Dominik. Best regards.
