Christmas Loop at DS / It's a Wonderful Shop

I've recently spent some time examining the various WDW Christmas loops. Can anyone speak to the Christmas Loop heard outside of the It's a Wonderful shop (on the backside of New York Street next to Mama Melrose's at Disney MGM Studios at WDW) or inside the shop itself? Is this a duplicate of the Epcot Christmas loop or, perhaps, the Main Steet loop? ??? And, does anyone know if a recording of this loop has been obtained? Thanks!
