I often find the quality available on AM to be superior to other platforms.
All the big ones also require a high quality master to be uploaded exactly because if any post-processing is needed it won't impact quality as much.
Apple would have to implement requirements for dynamic range, something that is somewhat feasible now with the ascendancy of LUFS as a measurement standard. But I doubt they'll actually impose rules.
That's too bad, because our only hope to reverse this idiotic trend is for the delivery conduits to say nope to ruined trash. Netflix has set technical requirements for content acquisition; Apple could and should do the same.
What makes this crime all the more galling is that dynamic compression can be applied by the playback device. You don't have to ruin the recording. My mid-'90s Ford CD player had a simple button on it, labeled "Compress."
Weirdly enough, I've noticed this happens with and without the sound normalization feature enabled.
