Here's a real gem of a CD for autism and other developmental disorders. 

Created by the musician dad of an autistic son; Vico.  This CD is rock and roll that both parent and child can enjoy.   The songs are familiar tunes but the beat is pure rock and roll! Sixteen songs total and include classics such as  

The Wheels on the Bus
London Bridge
You are my Sunshine
ABC Song
Itsy Bitsy Spider

Each song is catchy enough to keep your and your child's attention, yet slow enough so that the songs are intelligible and sing-able.
