Does music help your baby sleep? If so, what albums would you recommend?

I'd recommend classical music. In both my girls(when they were still babies), it helped them have a deep sleep even though our dog, who likes hanging around close to our room window, is barking loudly outside. Now that my girls are a 2 and a 4yrs old, i tried making them listen to my kind of calming music when we had loud guests and it's their nap time already. It made them sing along than sleep. They really love singing so I thought music without lyrics will do the job better. I'm planning to go back to classical music.
