Custom Kid Song CDs

Boston2Bermuda

I am tired of buying CDs for the car and not being able to recognize any of the songs.  Does anyone know of any websites that will let you customize the songs on a CD and then purchase it.  I understand I could burn a CD after downloading songs but I do not have the computer capabilities.  Please let me know...I am dying for a little Wheels on the Bus and Itsy Bitsy Spider!
