Sound Isolation Clips (worth the money)
Just how sound proof are you wanting it to be?
I just finished our basement last year. I put no insulation between the joists. Nothing. Just drywalled over them. I even used can lights, which means there are openings in the ceiling drywall.
My basement is not soundproof, but it's pretty quiet. Very little noise between floors. This might be due to it being an older house, with pretty massive joists, and oak floor on the main level. Even so...
Unless there is some reason you want to totally soundproof your basement (recording studio, etc.), I would think that rolls of fiberglass insulation would go a long ways toward a very satisfactory finished product.
Just my 2 cents' worth.
