McDonald's is partnering with Sony's Connect download service to offer free digital music to its patrons.

Through the international "Big Mac Meal Tracks" promotion, McDonald's customers who buy a Big Mac Extra Value Meal will receive an access code that allows for one free song download from the Connect music store.

The six-week promotion kicks off June 8 in the United States, Puerto Rico and Canada; it will launch in early July in the United Kingdom, France and Germany.

For Connect, the partnership means increased visibility and a way to draw traffic to its online store.
