The fourth Thursday in November marks probably the most widely celebrated American holiday with seemingly no songs to go with it -- only food (and football games, and then leftovers). But we've found this is not entirely true: here are no less than 27 tunes (a couple of them more than a quarter-hour long!) that will help you through the cooking and digesting of turkey, cranberries and sweet potato pie, including songs about those three foods. So be thankful.
