Can anyone recommend any good sound insulation materials for use between the floor joists of my basement ceiling?

Has anyone ever used resilient channels for hanging the ceiling sheetrock? Resilient channels are metal strips that attach perpendicular to the bottom of the floor joists, and then the sheetrock is screwed to the metal strip between the joists to minimize transmission of sound through the screws and joists. Are these overkill, or do they actually provide a tangible benefit?
