Think this is what your saying (from subfloor moving down to HT ceiling):

subfloor | safe&sound | air gap (?) | pink Insulation | clips & channel |
1/2" OSB | green glue | 5/8's wall board | plaster (?)


Correct. I wanted to add the osb strictly to have flexibility for mounting speakers or projector while also adding some mass.

Your ceiling will certainly have more mass than mine. Fortunately I don't have to worry about the walls too much but I will probably still add clips and channel along the inside dividing wall and on the outside of the stairwell. It'll all be insulated with safe n sound.
