What country still has music?

When you look backwards you selectively limit your view to the best music of an era, whereas the music of today benefits from no such filter and of course seems worse in comparison. An interesting take on this effect are the Owen Wilson and Marion Cotilliard characters in the film "Midnight In Paris".

Here's a listing of best selling artist by decade. Basically, from from the 1980s onward Madonna and U2 rule. Click on the links at the top of the page and you can narrow your data to specific years.

As far as I can tell there was always good music and really bad music popular in any selected year.

If you widen your definition of what constitutes music to infinity, then of course it's going to continually be recognized as such but you'll be desperately searching for ways to ascribe it as a pleasing experience. U2 was on the envelope from the start imo. I do like a few of their tunes. Sweetest Thing is my fav. Best selling artist lists have nothing to do with this issue. Even if you like it, that doesn't necessarily make it music

Some might make the argument that no music since is the equal of Bach's.
I think there is some validity to that argument.

At one time what we call 'classical' music was the 'popular' music. It's now called classical because it has stood the test of time. That is the ultimate measure of any music, does it last! A good thing to look for is, what music do they use in the movies to represent a certain time or era. Not perfect, but a pretty good indicator of which music had the greatest resonance in society doing any given time.

European Classical music is not superior to all other forms of music. A lot of it is awesome, and almost as much is boring.(sleep inducing) One man's opinion. And since music is not a natural phenomenon, but man-made, then man can judge.
The GREAT music can / does jump across cultures and societies.

Okay. But in keeping with what I perceive the OP's topic is, there comes a point where all variations, melodies, and especially harmonies according to what actually works, have been explored. After which "only" dissonance remains,not to be confused with Jazz. That, or what we're subjected to of late, straight monotones of higher and lower sequences or non-melodic ones. The stuff that was tossed over the shoulder hopefully into the trash when the real stuff was being written.
