It's all about investment. There was a day when you could not hear your favorite song unless you bought the album, or it came on the radio/tv. These days, an album comes out on Spotify, and most people will be listening to it for about a week or two, then they move on.
Music was not on demand the way it is today, so it was much harder, and took way longer for songs to get played out. That's why the older the person is, the harder they Stan for their music.
