Christina Agueilera's ``Light Up the Sky'' showcases the maternal protection of animals such as the mountain goat and the cheetah.

Tyler's recently released country song "RED, WHITE & YOU," is a perfect backdrop to "Summer Wild." This episode shows how several North American critters–prairie dogs, hawks, and wild mustangs—like to spend their summer vacation.

In "Crazy Love," Goulding uncovers the amazing (and hilarious) lengths some animals go to to attract a mate. Her hit, "Something in the Way You Move," sets the mood for animals as diverse as polar bears and garter snakes.
