They say there's no end only beginning. The bedroom at the very beginning is the same bedroom as the anti bedroom just innovated and made over. So whatever she is looking for (I think the gold) it was in the bedroom all along. I think she only had to go through the transformation. The anti bedroom could also represent her after the transformation since she was pure at the beginning but now she is dark and changed.
So if each room represents an era/album of hers, and R8 is an updated version of R1, that means Anti is really just the 10th year anniversary edition of Music of the Sun with three new tracks!
