Right, let's see here...
Johann Sebastian Bach - All that has been uploaded as of yet is on megaupload (I think). In desperate need of an update. For lack of specific works, I would much appreciate if someone would upload the following: St. John Passion (BWV 245), The Art of Fugue (BWV 1080), and St Matthew Passion (BWV 244). All these are stated without having some specific conduction/performance in mind, so I'll just leave it to the good taste of the uploader.
Anton Bruckner - Symphony No. 8 (preferably by the Berlin Philarmonic under Günter Wand, but any good rendition would do just fine)
Autumn Tears - Love Poems For Dying Children... Act I (It would be interesting to hear if anyone has this as I simply cannot find it anywhere. Similar to dead can dance in spirit, some deem it better)
That is all for now.
