Animal Alphabet Songs, by David Polansky, a Boston-area kids performer, is a terrific CD to listen to with your kids.  There’s a song for every letter of the alphabet, and each is about a different animal: A for alligator, B for bears, C for camel, and so on.  The lyrics are very clever, and the songs are done in different musical styles.  It is music that is really entertaining for both children and parents.
