I have used the barrium filled vinyl barriers, and z type sound channels and was not impressed for the sever cost.
I have also built a room in a room with double drywall at a lower cost and was impressed. Hang the strips to attach the drywall layer to with wire attached to the joists of the ceiling above. Supper low cost and supper decoupling. Make certain that when you join the fake ceiling with the walls that you don't make it rigid. Leave 1/4" gap and fill it with silicone sealer. Then just paint over it. Not as pretty looking at the ceiling/wall interface but works and cost dirt.
foams will not even slow the bass down.
