Music for a dark wedding?

My betrothed and I are planning a wedding and I really could use some help in finding some music. Its a formal ceremony that has an underlying gothic/dark feel to it. He isn't dressing up as a vampire, just a black tux and I'm in an ivory strapless corset style dress that reminds you a little of what Victoria in corpse bride would be wearing were she a little less conservative. All in all it is a very elegant occasion/. Neither dark rock/hard core music nor the wedding march works very well with the overall style we are trying to achieve. I think I might go with Beethoven's Moonlight Sonata for the walk down the aisle but I really would appreciate any other suggestions. Plus we need more then just one song for the ceremony. Thanks!!
