I think that normalizing loudness is a particularly tricky topic for submissions that have a really rough mix - e.g. the drums kick in late and are way overbearing, stuff like that. Inexperience can easily make for fluctuations of 6 dB, which would mean a departure of maybe 3 dB in the mean - so, part of the song is 3 dB louder than the rest, and the rest is 3 dB quieter. The same can happen for a song with two distinct parts - in a more dynamic mix, 6 dB of difference are not at all out of the question (and not as extreme as the examples brought up earlier). There's really no way to stop this without going into audio-level compression (which we seem to agree is not a good idea).
I mean. Yeah, the loudness will hopefully vary within a track. Dynamic range is a good thing that cuts down on ear fatigue. And 6dB isn’t that much variation in the first place.

Out of curiosity I tried YouLean on my wiener dog song and found that it had a LUFS of -8 with a peak of 0. So I reduced its pre-limited gain to get -14 and lowered the limiter peak to -1. Listening to it side by side with the version on Spotify, the overall level sounded the same and I didn’t notice any change to the bits that YouLean identifies as peaks, but it’s also a fairly simple song without a lot of dynamic range. I’m very curious to hear what this change would do to some of my older tracks, although I’m worried about falling down the rabbit hole of wanting to remaster (and rerelease) all the things.
