Martina McBride's "How I Feel" will be used in a new TV and in-store ad for Crest Nature's Expressions.

The song will also be downloadable for anyone who buys one of the products. Fans and toothbrushers alike can enter the UPC code at Crest.com to get the song. Then Crest will make a donation to the Crest Smile Shoppes at the Boys & Girls Clubs of America for each download.

From a press release, Martina said:

I chose the song "How I Feel" for my partnership with Crest Nature's Expressions because it's all about the little things that make me smile and being able to share those special moments in life with a healthy and happy family.


As for the Boys & Girls Clubs of America, it "comprises a national network of some 4,000 neighborhood-based facilities annually serving more than 4.6 million young people, in all 50 states and on U.S. military bases worldwide."
