Ok..as long as its not for a perv thing...lol...
They make special sound deadening drywall and channels that are screwed to the studs that help isolate sound. Also the best I've seen is to use a larger plate and off set the studs so you are not attaching to both sides of the same wood. You could also build a false wall slightly off from the current one and make sure there is no contact, then place 1" styrofoam with taped seams between the walls.

Never done it myself..just what I've read.
If you offset the studs in the wall and screw the drywall to the offset studs on each side of the wall, sound doesn't transmit through as well as well. You can also insulate between the studs with polystyrene foam. It means you have 2X as many studs of course..instead of 16" centers you will have 8" centers.
It kind of depends on what sounds you are trying to isolate.. Bass sounds transmit by vibration in all sorts of materials...higher tones go through the air.
Thats about all I know..but if you use the advanced search function here, you'll find several posts over the last couple of years that have more info. The makers of drywall also have info on their sites I think.

Avoid foam at all cost. The fiberglass you mentioned is fine.
Decouple the new drywall from the original studs to minimize the conduction. This can be done by converting the coupled single stud walls you have to decoupled staggered studs: Building a Staggered Stud Wall | Soundproofing Company (http://www.soundproofingcompany.com/library/articles/staggered_stud_wall_construction/)
Add the R13 fiberglass you mentioned. Nothing thicker or more exotic.
Double 5/8" drywall.

when i try the 'search' feature-i get a page that says'DATA BASE ERROR. am i doing some thing wrong??

Gunguy's offset studs are actually the staggered studs I was referring to. Again, use fiberglass, not foam, but otherwise he's right on
