I'd love it if they used some Black Sabbath as, obviously, loads of that music would lend to some great imagery. Honestly, I could see the remaining members of Sabbath signing off for use of some of it just because of their devotion to Ozzy and the loss they also felt when he passed. If you followed any of the tributes, especially in Birmingham, England, much of it related to Sabbath as well - the murals, the special events, etc. Anyway, even if it's just Ozzy's solo works, there is plenty (more than what they could fit, actually) that would make a great house.
On the Ozzy train of thought - I wonder now if they will wait to announce this house until July 22 which would be one year since he passed. While I HATE having to wait for official confirmation, I'd be really moved by such a tribute.
