To answer that I will give you this example
I used to often wonder why so many 70s bands made such awful albums in the 80s.
Then later when I would read about these bands I found out the reason for these awful albums was because of drugs, booze, bands hating each other, bands not bothered any more, bands running out of ideas, different band members recording in different continents, endless line up changes and so on and so on and so on
And when I read all of these things about why these records sucked I was not surprised in the slightest because I knew these albums were nowhere near as good as what had come before.
Back then I knew no reasons why they should be that bad or no reason to expect them to be bad before I heard them. they just were, you could hear it in the music.
And I was a person living alone with a record player on an island
