You think you cannot appreciate art music. Well, you have not been properly introduced. Pop music needs little introduction but art music does because we do not automatically know our way around it. You know your way around a Lacrosse field (and so do I - played it like a redskin, lost a tooth).
This is an excellent intro, much better than I got in college: The 30 Greatest Orchestral Works. Readers know how much we love Bob Greenberg. My Mom loved him too. Buy it, or ask me to lend you my copy (which is actually on loan from a friend with whom we exchange Great Courses).
The Great Courses is one of the most life-enriching things we know of. We generally do one session of some course every evening.
