Au contraire, mon ami! Actually I'm just going to do a very brief comparison of the music scene two hundred years ago with the music scene today.
Who were the most famous musicians in the world (well, actually, Europe) two hundred years ago? There will certainly be those who might argue for the opera composer Rossini, but in 1813 he was only twenty-one years old and still to achieve his great renown. I think it would be a fairly easy case to make that the three most famous musicians around 1813 were Mozart, who had passed away in 1790, but was still very well-known and more highly regarded than during his life; Haydn, who passed away in 1809 and was at the time the most highly-renowned musician in Europe and Beethoven, forty-three years old and with the triumphs of his Third, Fifth and Seventh Symphonies just recently in the public's ear.
But who are the most famous musicians of today, 2013? Ah, that is where it gets interesting. You could certainly argue over this a lot, but just looking at album sales, the biggest selling albums since 2010 were by Adele and Eminem. Let's add a third artist: Jay-Z? Rihanna? Beyoncé, Katy Perry? Take your pick really, it won't affect my point.
Now let's compare them. I'll just pick the first individual piece that comes up for each artist/composer on YouTube. First, Mozart, Symphony No. 40, first movement:
Haydn, Symphony No. 94, "Surprise", 2nd movement:
Beethoven, Symphony No. 5, first movement:
Adele, "Rolling in the Deep":
Eminem, "Not Afraid":
The best-selling single so far in 2013 is apparently "Get Lucky" by Daft Punk:
Any doubt that music certainly and civilization probably is in decline?
