Thats a good point you made. Peoples tastes do change, I know mine have. I used to be big on country when I was like eight, now I'm 15 and I like bassically anything with the word rock in it. Most people at my school who like nu metal also like one or another style of music. Its better to have a broad taste in music than a limited one.
And God said, 'Let there be rock!'
