Dedicated Music Room Recessed Lighting (High Hats)?

cissado, thanks for the suggestions much appreciated.  I will address all of those areas.  The sheetrock is going to be glued and screwed, so maybe some Green Glue on the supporting braces between the joists is a good way to go.  Along with taping and wire on the other locations.

Perhaps you could spot check the ceiling/walls/room by hooking up an inexpensive tactile transducer to an amp and sound source (they are $10-$20 @ Parts Express)?

A CD with sound sweeps, like the one by Ayre, should do the trick (along with a long run of lamp cord/speaker cable).

OP, do something now, you sound like you want to. Just do it.. Get some high temp stick on stuff and seal the heck out of it.. Silicone is expensive, There is expanding fireproof, soundproofing foam. Tightens EVERYTHING up... Easy to apply.

Put that stuff ON and let it air a bit.

Tighten all the wires in the rafters too, a little dab will go a long ways for for rattling cables laying on rafters

No huffin the fumes OP, that's a no no!

Enjoy the new room... It won't be spooky for long. VERY quiet with no wall board up though, only insulation. It is spooky, no room bounce..

"Glued and screwed" is the route I took but with a couple extra steps a long time ago converting my garage to an audio room. Used double 1/2" sheetrock along with 3 headers between each stud. Along with concrete slab this room was solid.
Here's a little story from a few years ago.
During a period of sanity I temporarily left audiophileville and the structure was modified to function as a garage again.
One night three years ago a young drunk driver decided my house was a street and plowed right into the outside corner of my garage. The siding, the corner, corner of the garage door, fence, and landscaping were pretty messed up. The interior a couple cracked studs and a little drywall wrinkling. The insurance company could not understand initially why the garage did not partially collapse. Not a common building practice that our kind strive for I guess.
Anyway, pertaining to your vibration concerns Herbie's advised me about Permatex Blue. Stuff is used for gasket sealing and is also great for vibration control. It is the consistency of toothpaste and solidifies in about 30-60 minutes. I have it in many components with excellent results. Maybe it can be a benefit in your project.

oldhvymec,
I should have mentioned that the entire room was sprayed with commercial sound absorbing open cell foam.  Then Roxul SAFB to fill up all the cavities, so the wires are all or nearly all are foamed into place.  I have yet to pull some of the Roxul out from around the "cans" mainly because I hate that stuff.  To round out the picture for you the floor is concrete slab. Not very much sound energy can get in or out of the room. Thanks.
