You make several mistakes.
First, just because something is popular does not mean it is bad. Similarly, just because something is rare (e.g. a bunch of black dudes jamming in a bar) does not mean it is good. You are confused on this one. When attacking music you should always attack it based on its constitutive elements, on what is within it, not based on what is outside of it and certainly not based on a symptom.
Second, just because something is simple does not mean it is bad. Similarly, just because something is complex does not mean it is good. You need to forget about linearity. Ordered simplicity is superior to disordered complexity.
Third, though “Blue Danube” is one of the most popular and one of the simplest classical pieces, it is certainly not a pop song, in a sense that there is a great distinction between it and 20th century pop music, including contemporary classical music, neoclassical, minimal and the similar (e.g. Ludovico Einaudi and Philip Glass.)
Fourth, the best way to demonstrate the superiority of a genre over another one is to pick one of its weaker representatives. “Blue Danube”, whether you like to admit it or not, is above anything Mahavishnu Orchestra ever did (even Jan Hammer’s casualesque ambient music, call it elevator music if you will, is more engrossing.)
You are an imbecile, Lev. You should just stick to your jammers and forget about discussions.
