Just a simple theory, may be I am wrong:
people who grew up with IR music (peak times) must be in the mid 25's- mid 30's may be 40's, and ARR music in mid 20's. So some memories dont fade away just as quickly as we think, We do attach ourselves with music, time, place and what not, so IR going out completely or ARR going out completely is just a fallacy and will not happen atleast for the next 25-30 years. what do you think?
