Here is a gallery of a few of the CD projects produced by Music Mill Entertainment through a strategic partnership with Cracker Barrel Old Country Stores. Our line of American Music Legends CD's sold in-stores from 2004 - 2011. These titles are no longer available. Many, which featured rare audio and photos, are considered collector's items. A new and proprietary technology was used when producing the children's CD's for the restaurant chain. When the disc is inserted into a computer, several different coloring book pages can be printed. The combination of travel songs and coloring pages make for fun family road trips.
