Ok I've read your attached post and I recall your situation quite well....in your specific situation the only thing I would do is the 1/8" MLV and Green glue with new 5/8" sheet rock...even if you had the space to do a floating wall it most likely wouldn't be worth it due to the massive flanking issue you will still have due to the common wood floors and ceiling height...your best bet for the money would be to do the direct apply approach mentioned above followed by......covering the wood floors and adding as much soft surface to your unit so you can atleast absorb the sound faster to reduce the echo effect and massive reflections that are happening now which indeed is compounding the problem.

please note that we do *not* have common hardwood floors. it almost feels like that,though.
i pulled back the wood trim against the drywall/wall, and the hardwood floor was cutoff right there - so it's not a continuous hardwood floor to the neighbors.

however, im not sure where the coupling is coming from that. (probably through the concrete slab?) probably little i can do about that but an extra layer of drywall will probably help the impact noise being transferred through the drywall.

any recommendations on what to do with the tops of the new drywall? should i (acoustic) caulk on top of the drywall and mate it with the ceiling, to help fill that ceiling gap?

Yes the slab would be the connection which has a transmission speed of 10,600 fps!

And yes caulk EVERY gap, around perimeter and any penetrations.

Keep in mind when your doing sound control you are building a fish tank...if water can get through so can sound.
