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.
Imagine you just obtained a finished, commercially produced and mastered
song.
You play it on your music system with the volume set at 5.0. It sounds a
bit too quiet, so you turn it up to 7.0.
Did you change the mix? Did you change any aspect of the production process?
Hopefully it is clear that you did not.
Normalization is *EXACTLY* equivalent to this process.
