Would it be worth the time to cut strips of drywall and glue it to the underside of my first level floor between the joists?

I really want a drop ceiling (using ceilinglink) but want to get some sound dampening between the 1st floor (dining room) and basement home theater room located directly below..

Stuff it with pink would be easier and cheaper

I was thinking of doing both. Stuffing insulation in where possible.

If your dining room is hardwood, adding strips of drywall with green glue under the subfloor will make a big difference, do two layers. PM Snickers1 he was the last one I remember doing this at his place.

I put two layers of 5/8" drywall in a GG sandwich between my floor joists. I noticed a very large improvement, and I have carpet on the floor above me. I can't imagine not doing it with hardwood upstairs. It's a bit of work, as each joist cavity varies a bit, but it's not crucial to seal the joists; you're really just adding mass to absorb the footfalls.
