How people listen to music changed. They will sit and watch an hour TV show or even a two hour movie if it is really good, or it doesn’t even have to be that good maybe, just OK. The number of people who will regularly solely just listen to music for an hour is probably drastically reduced now. The number that do so on a good home hi-fi system is no doubt even more reduced. So almost all aspects of popular music reflects how it is now normally and regularly consumed—as background music composed of individual tracks while something else is also being done, driving, cleaning, exercising, working, surfing the net and so on. It comes through earbuds or crappy computer and phone speakers, normally on shuffle play.

If they have a "home theater" surround sound system then they have a readymade system to play their CDs (or even DVD-Audio discs).
Some bands that have final cut can still make this happen, but I'm sure that most acts have accountants and focus groups and data analysts deciding which songs go where based on maximizing profits on singles.
It was nice while it lasted though!
