"The Real Reason Why Today's Music Is Starting To Sound The Same..." - I watched this few weeks ago. He is an interesting fellow, but with this topic, too much voodoo theory smile

My take, it comes down to personal perception and accessibility, and while sound obviously plays a part, it's not it.
30 years ago, unless you had a friend or two who had a taste and a collection of non-commercial music, how would you broaden your horizons? TV, Radio, or a club in a city that had open mics and was friendly to new and diverse non-cover bands. But for the most part new (non MTV/VH1) music was "discovered" by word of mouth.... and a good tape deck smile

With near unlimited access to 100+ years of recorded (audio) music... When you heard too much of everything, you are harder to surprise. You are too quick to find analogies in melodic and harmonic patterns with something you heard before. Those layers create illusion that "Music Is Starting To Sound The Same".

There are hundreds of amazing and thousands of great and unique active bands. As I've mentioned, it's all in perception.... and desire for discovery.
