How to report Apple Music low quality tracks?

My question is: Does anyone know what the best way is to report poor quality Apple music track to Apple? I don't know what their process is to fix or replace them, but I would be surprise if they didn't have a procedure.

I recently came across an album that sounds really bad. It sounds as if it were unconverted from a lower quality compression.

I thought it was me, my headphones, or that I was merely getting a low quality stream or download, so I opened up iTunes on my mac, downloaded a local copy of the tracks, confirmed they were Apple Music 256k AAC, and played them. They also sounded pretty horrible.

It so happens that I own a copy of that album from the iTunes store. I re-downloaded the store copy, played it, and that copy sounds (nearly) indistinguishable from a CD and sounds great. It's the 256K AAC iTunes store copy.

Doing an A/B test, the sound quality is night and day despite both tracks being 256k AAC. I can't even dismiss this as a "slightly" inferior copy. It sounds as if the copy was converted from a 128k or lower quality.

Please, no judgement on the taste in music. This isn't my normal genre. It's just an 80's nostalgia guilty pleasure.

Artist: Roxette

Album: The Ballad Hits (2003)

(the album cover is white with a heart made of raspberries)

Track: ALL

The iTunes store = excellent quality

The Apple Music = bad qulality.

I tried comparing the iTunes store sample

However, the Apple store copy sounds bad enough so that if you just listen to this one song you'll hear how distorted it is. It's even more striking when you compare it.

Personally, it seems like a pretty rare occurrence. I would be surprised if there weren't other older files in the library that were not compressed from a good source. If I like the music that much I have no problem buying a good copy but it would be unfortunate to listen to something I don't have an interest paying for that sounds like poor.

Thanks.
