it is not surprising that people express a distaste for anything. there is an expression in latin that is very old and expresses such a thought:
de gustibus est non disputandem (i hope i spelled the last word correctly)
there are a lot of people who are iconoclastic when it comes to pop culture.
i certainly think that a love of music is very common among the populace.
i think there is a connotation implied by the question, namely a superciliousness regarding certain genres of music, which may account for a small minority of audiophiles in the world.
it would be interesting to find out , among audiophiles, what percentage does not like popular music.
i suspect that more than 50 percent of audiophiles have an appreciation of classical music. i suspect that this genre is the least popular, and it may explain why there are so few audiophiles. it follows logically that if i am correct, the number of audiophiles may diminish over time, if there is a high correlation berween age and love for classical music.
