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.

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

One of the "objectives" you can get Rives to look at in a design is soundproofing. While that was not a concern to me, they were great to work with (you can find out about them from other forums or their website).
