quoting the response to a frank zappa quote
"There is a reflection in many of the music people listen to now. I myself am not really all that into classical but i still respect it for it's greatness. Some people don't give this type of music a lot of credit when really they should because its awesome." - Victoriano Franco III
Though this idea was influenced by a quote of the great Frank Zappa, I still find myself in full agreement with Mr. Franco's point of view. I am not into classical music either, but it is, undeniably the foundation of all recent music, or that which was written/performed within the last 300 years. Furthermore, it is often much more complex and makes more use of different aspects of music theory. Also, there are only a limited number of chord progressions in existance. Being, for lack of a better term, the guidelines to songs falling into the category of structured music, inevitably people will write songs that, in essence, have already been written.
