Music for kids (of all ages)

I'm going to come right out and say that I don't like children's music that contains children singing.  It makes my skin crawl like the smell of pink J&J lotion.  When Olivia was born Steve and I went through our CDs looking for lullaby music we don't mind hearing over and over, like Sarah McLachlan and John Denver. 

That being said, my sister-in-law gave us a CD they enjoy called "Blue Moo" which is designed for kids but is clever and catchy for adults.  For example, BB King sings the "One Shoe Blues." I love it and other Sandra Boynton albums like "Philadelphia Chickens."  I'm open to suggestions if you guys have other adult-friendly kid music, too -- just leave a comment so we can all enjoy.
