What songs so you find yourself singing to your infant?

My seven week old will fall asleep if I sing My Chemical Romance to her! It's the album I listened to when I was pregnant, not sure if that has any bearing on it! My four year old daughter also loves the album though so it gets played a lot in the car! I tried singing some more gentle country songs to her, like Oliva Newton John and Shania Twain but no, she will only settle to MCR! Looks like I have two emo babies!
