In addition to children's classics like the "I Want a Hippopotamus for Christmas" song, there are a few others that are newer to radio. One that always makes me tear up a bit is "The Christmas Shoes." You'd have to have a heart of stone not to love the message.
At the absolute other end of the spectrum is a new song by Toby Keith, who is not not known for his political correctness by any stretch of the imagination (see exhibit A: "The Taliban Song").
In reality, two of my favorite Christmas songs are "Mary, Did You Know?" and "Do You Hear What I Hear?" Whatever your favorite is, be sure to enjoy it this Christmas.
