The other option, assuming you don't rent, is to hang celotex sound isolation board on top of the drywall. Won't look that pretty, but you can hang drywall on top of that for excellent sound isolation. I also think that building another room inside your current one is a good idea albeit quite expensive and fairly time consuming.
Can I soundproof a rec room that's already built?
I live in a three story townhouse. I want to listen to my stereo in the recreation room in my basement at relatively high volumes from time to time (also home theater). The place already has drywall ceilings and walls.
Am I kidding myself that I could make a big dent in soundproofing even though the walls are already up? Would it just be a waste of money? I don't want to just cut down on some of the sound from going upstairs and into the units on either side of me, I want to cut down on a LOT of the sound.
p.s.
I am not willing to tear down my walls and ceilings.

I have even thought about moving into another house but I can't really afford a single family home in the D.C. area.
