A correct statement based on three wrong assumptions.

1) That I've lost interest in music myself (I didn't).

2) That whether some other people might not lose music was disputed. Perhaps you imagined me as some strange creature in a cave that has never heard or known of people that maintain their interest in music to their late age.

3) That the fact that some other people don't lose interest in music is relevant. I was making a general statement ("it's also rare"). Most people do lose interest in music compared to their younger years. That's not some fringe claim, it's borne out by buying patterns and studies. People tend to stick to the music of their youth time and again. Even the new artists they discover tend to be of the same genres and styles in vogue when they were younger.
