I'm starting to make a playlist for the Nano that is going in LO's room. I have several "quiet" songs on my own "Sleep" playlist that I am going to include, but I want to download some songs of his own. I love the Rock-a-Bye Baby CD's but don't have any. Are there any other good ones that you guys like? Not necessarily lullaby/baby songs, but low-key music that you love?
