I have such an emotional connection to music anyway, but Christmas music really puts me over the edge.
When I was young, I loved the silly songs like Chipmunks Christmas and "Jingle Bells, Batman Smells". But I always loved the song Away in a Manger. My childhood church sings a song "Jesus, the Morning Star" from a children's program we did a long time ago. It still grabs me.
I cry when I hear "Mary, did you know?" Oh man. Gets me every time. I love the version currently on my myspace page by Kutless. And "Mary's Song" by Amy Grant gets me too. (I've signed that a few times at a few different churches and it leaves me emotional.) I guess because I'm a mom, I can't imagine birthing a child I knew was the son of God and that I wouldn't be able to protect him from his future and fate.
There is just such a pulling for me with lyrics and how people express themselves, happy or sad. So if you see me crying while I'm singing in my car, don't be surprised. Just check the radio stations to see which song it is making me cry this time.
