Phil Collins And Unintended Consequences.
CDs were promoted in terms of sound quality and digital compression. They were also smaller. But marketing expert, Phil Collins made the interesting point that it's also the first time music was one-sided. While this means that you don't have to turn it over, it also means that you don't need to be encouraged to turn it over.
Prior to this, albums were created so that the first and last track on each side were particularly strong. They focussed on keeping the listener excited/empassioned and wanting to turn over. On CDs, it's alleged that the first three or four tracks are the strong ones and the rest are filler because the assumption is that people will relisten to those and not go too deep into the album.
Whether or not that's true, it's clear how people would react. They would realise what was going on and, once the technology arrived, they would opt to download only those tracks they wanted and completely undermine an industry.
That's what happens if you don't bother to enthuse your users. They may not have to turn over anymore, but they will always have the option to turn off.
