I appreciate some classical music every once in a while, especially since I pretty much grew up hearing classical music at home and y'know..band and all.
Uh, you might like this composer: Abel Korzenioski. If you look on iTunes, there is a free podcast of the music he did to go along with this old black and white movie. It's called Metropolis: Symphony of Fear and it's several songs from the whole thing, and I think you'll like it. There's a little bit of opera mixed in (kinda) but I think you'll still like it.
And my favorite song is Danse Macabre. It's an amazing song if you haven't heard it already. It isn't by Abel...look it up on Youtube to listen to it. The song's a little over 7 minutes and it's quite interesting.
