Hey, I don't think we like classic rock because it was first, or because it progressed anything in particular. We just like it. I like lots of modern rock too, maybe even more so now...that is, modern *rock*, not *modern* [derivitive].
A good example of what's going on here...I think other types of music (techno, rap, country, etc., etc.) sound more or less the same 80% of the time (there are exceptions, obviously). I'm sure there's plenty of people who like those genres and think the exact same thing about rock :P. That's just how people are...you like what you like, and things you don't like, even if you can appreciate them, do tend to sound the same a lot of the time.
And then there's just music that *does* sound the same
Just because I like more recent rock now more than classic rock (which I used to like more) doesn't mean that classic rock has somehow degraded in quality
It just means my tastes have changed.
