Music just gets in the way of constructive thought, and once you have heard a song a couple of times you've heard the song.
While I realize you identify as one of the 1-3% who doesn't like music, this statement is not true for many, many people, if not most. I'm sure this is an argument you've had to make many times in your life when the topic of music (one of the most common things to converse about) comes up, but just because you believe it doesn't make it true for everyone. Hell, you dislike music, so why would you look further into it?
Nothing ever becomes real till it is experienced -- even a proverb is no proverb to you till your life has illustrated it. -- John Keats
