It is equivalent to the guy who listens to the music
turning the volume
dial on the amp. It does not affect the mix at all.
If you export too soft, s/he will have to turn up the
amp.
Although the whole idea is to load commercial songs, by genre, to compare with. That
adjustment would be done by hand, as part of 'mastering', as well as any other
final adjustments. The resulting CD (or individual pieces along the way) being played in
various places and again compared to same genre commercial products.
One positive side effect of normalization is that you
get the best
signal/noise ratio for the exported target (usually 16bit). If the
loudest peak is at 0dBFS the whole [16bit] range is available for
dynamic range. If the digital peak is at -6dBFS you get one less bit
dynamic range (with integer encoding).
So far I tend to see it as part of the craft of doing the final adjustments, be them about
loudness, compression, EQ, etc..
It might be part of learning.
