Just a curious question, won't be a poll. Do you think your taste will be different 15-20 years from now? More "conservative" that is, tending to like Baroque or Classical? More "liberal" that is, tending to like 20th Cent. and Contemporary? Or, simply more open to all eras in general?
My prediction for myself: I may turn into an avid Stravinsky/Bartok/R.Strauss/Mahler fan (all people I dislike in the present) in the next 10 years, then turn to Serialism, and then have a reactionary period where I will listen to Baroque/Classical eras (more likely to happen 40-50 years from now, if Lord-willing I live that long).
I'll see if it actually happens.
