This has to be a formula somewhere. How does music change to your ears over time?
Example: Jungle, or Drum n Bass, used to give me anxiety. I was a “househead” the whole way. Now? Jungle sounds fine to me, and harsh noise gives me the same almost seizure-inducing feelings.
Will that change over a ten year period? I guess it is inevitable that eventually the music of today becomes the classics of tomorrow, no matter how invasive or non-musical it seems right now.
Let me see if I can start working on the equation right now:
f(music)= {db(music)/tempo(music) + number of fans(music) x band name(music) } / number of years performing (music)
