I really noticed this when listening to radio stations in Apple Music. Why is that? It’s so annoying because you constantly have to adjust the volume up and down.

Adding dynamic range compression to already overly compressed music is NOT the answer. Music is NOT a TV commercial and preserving as much SQ as possible is important to many people. Apple does have an optional program called Mastered for iTunes.

[doublepost=1550413911][/doublepost]Actually just remembered that Apple does offer you the option to turn on compression if you want. It is called Sound Check. Bad for SQ but it does help do what you are asking for.

Sound check doesn't apply compression to the music.

It detects the average loudness level of the song ("RMS" level) and adjusts only the the playback level of different songs so that their perceived loudness is more similar to each other.

As an aside, streaming services are actually great for those who care about music dynamics because a lot of services (like Spotify) level match songs so that they play at -14 db RMS, which is lower compared to commercial pop music from a few years ago.

So there's far less incentive for engineers to slam and limit songs anymore, since they would just be reduced in volume on playback on a streaming service.

Gonna try soundcheck and see if it solves the problem. Thanks.

Indeed, Sound Check does not compress music, it just adjusts the gain (volume) as needed. It works pretty well, but (like the equivalent on Spotify) it's not a PERFECT solution and you'll still have some tracks sound quieter because they're otherwise mastered so loud that the gain correction turns them way down. This should actually encourage mastering engineers to stop brickwalling music (the classic Loudness Wars stuff), leaving plenty of headroom and dynamic range, and sounding good on streaming services which have volume normalization.

This still bugs the crap out of me. Any time I listen to tracks via Apple Music I have to turn the volume way up compared to where I would have it set if I was using Spotify or playing something via YouTube. I’ve tried everything in settings, EQ etc. and nothing works. So annoying.
