I don't have much on the ol' Zune at the moment, but that's because I don't have that much, either. Let's take a look-see:
-Verdi's Requiem by Robert Shaw & his bunch from Atlanta. I only like the choral parts because that's what I had to sing; wasn't a soloist so I don't really care about them.
Hooray for dies irae!
-A lousy recording of The Planets by Geoffrey Simon and the London Symphony Orchestra that had a low recording volume, so it's hard to hear at times. I need a better one; does anyone have any recommendations? A good and bombastic Mars will go a long way.
-A compilation of several pieces by Jean Sibelius, including The Swan of Tuonela, Valse Triste, Finlandia, and some others; it's a pretty good one.
I've also got a lot by various motion picture score composers, so if they count, there's always guys like James Horner, Basil Poledouris, and the like.
