Here is a free download:
You can download Dig a Little Deeper from Walmart. (I found this today on a free postcard in the apparel section at Walmart. It came with free stickers from the movie.)
It would go great on the $7.99 MP3 player I told you about here.
Also don't forget that if you did see the movie, you can enter your ticket stubs at DisneyMovieRewards.com to earn points towards Disney merchandise.
