Classical music is pretty much the only kind of music I listen to. It just strikes at the heart of my existence, like it resonates at the same frequency as something inside me.
It's so rich, full of emotional and logical twists and tangles, I don't see why more people don't enjoy it. Then again, many people would probably wonder why I don't like the garbage that tops the hit lists.
The best source of classical music? Here's a listing of internet classical radio stations:
Classical Live Online Radio Webcast - Classical Internet Music.
My favourite is Radio Swiss Classic. Very little talking (in German and French), and a LOT of classical music.
