Music

I heard this song in the Student Union today. It got stuck in my head... and it made me think of how music (in particular rock) has changed so dramatically from this:http://www.youtube.com/watch?v=9p88Rh3C_rQ To... I dunno, generic heavy metal song #567 The top comment at the link got me thinking about the concept of music having "soul" in it. I can tell what he/she is talking about. I don't think that every single piece of rock music today lacks soul (or maybe I simply have a differing perception of what "soul" is) but it is a noticeable change.
