music today isn't well-made.
That is extremely subjective and misinformed. There are millions of songs that are well made and the amount of well-made music has not changed in the last 50 years. The events that happened in the last 5 decades did not change the amount of well made music. The only reason you think music from the 50's-80's was better was because either you have a different musical taste or because good music survives. For example, do you remember 'Rock Me Amadeus' by Falco? No. You don't. That's because no matter to popularity of the music at the time, if it's not good it doesn't survive. In 2030, the same reason 'Rock Me Amadeus' didn't survive past the 80's 'Never Say Never' by Justin Beiber won't survive past the 2010's. On the other hand, the same reason 'Killer Queen' by Queen survived the 80's 'Hey Johnny Park!' by Foo Fighters will survive the 2010's.
