I would be happy enough if Apple wouldn't downgrade audio quality of old music (80's). Every time I play an '80s track on Apple Music the sound quality is very far from what I get from a current pop hit like Dua Lipa, Ed Sheehan, Lady Gaga, etc. And it is not because '80s music is old or has not been remastered, my car has a Bose audio system and if I play an '80s audio track from my personal collection (ripped CDs to iTunes), it just blows your mind in the same way that a new song does, the same happens with de radio, an old song sounds as good as a new one. But just play an '80s track on Apple Music and the quality is just flat, dull.
