Has anyone uploaded these yet?

there is no music for a darkened theater 3.

Music for a Darkened Theatre is Danny Elfman music, but it is not part of the box set, since it includes, non-Tim Burton work.
Vol 2 is a two disc set. A flac version can be found here (Thread 84020). Vol 3 is fan made, and not an official release. A thread for it can be found here (Thread 65858). Both of these have been out for years.

The Box Set Bonus Disc was a consolation prize for people who pre-ordered the box set before it was delayed. It consists of a kind 'Box Set Greatest Hits' and includes NO MATERIAL NOT ALREADY INCLUDED IN THE BOX SET. It's been online for months, in many places, including here (Thread 84561).

See? jon is on top of this. Music For A Darkened Theater is an entirely different thing than this new box set. As far as the anniversary box set is concerned, all music has now been posted here, and elsewhere. About a third were posted as 320 rips, the rest as 192. There is nothing else to upload, other than maybe the interview dvd, which is not allowed--no movies or such to be shared penly, remember. All there is to do now is to wait, and see if anyone ever posts upgrades. Patience now is all. And of course, enjoy the set.
