Recessed lights need to be insulated.If you cut holes in your ceiling for recessed lighting, this opens up a "window" for cold air or noise. So how can you insulate them safely?
This 5-minute video from Dr. EnergySaver is as pertinent to soundproofing as it is to thermal insulation. You have to cut holes cut in your ceiling to accommodate recessed lighting cans. If you don't have insulation in your ceiling at all, the hole makes an existing noise problem worse. If you do have insulation, you already know that you need to keep the insulation material away from the heat of the can.
This video demonstrates a rockwool product that you can put over the can in order to prevent heat/electrical issues. Of course you need to have an attic or someplace where you can access the recessed can from above the ceiling, not from below. It's a great solution if it fits your space!
I found these covers for $15 each at Amazon.
