In college, I worked in a university library sound archive, and my job was to catalog old 78's all day. I didn't need to listen to the music, but I could, if it seemed necessary to find some piece of information for the catalog record, and I would often make up excuses to listen the records to identify whether a particular instrument, for example, appeared on the track.
What I found, is that music of the 20's-40's was almost uniformly terrible. We don't think of those decades as a bad time for music, because we think of Ella Fitzgerald and the other good stuff. But in reality, it's like 60% Bing Crosby records (he's actually awful) and the other 39.9% is even worse. Good stuff exists, but it was definitely the exception.
Recently, I've been cloning an old popular BBS door game from the early 90's. The game is wonderful, and playing it, you might think developers of that time were finding all sorts of clever ways to create engaging, powerful games in 80x25 extended ansi. That's actually not true though. Most door games were terrible, but that's the one my friends and I chose to play every day after school. It's obvious why.
Some day, long from now, people will marvel at all of the amazing software that emerged on the app stores of the two-thousand-teens. They'll be wrong though.
In conculsion, all culture is mostly garbage.
