I have found a very effective way of dealing with corrupt CDs. The solution is surprisingly simple - just turn them into works of art! Like I did this for my kids....
I stuck stars and a half moon made out of chocolate wrappers on the shiny side to create an effect of night. Then I painted a sun on the side which had all the writings.
Since dollops of acrylic paint didn't hide the markings effectively, I finished it off by sticking paper bits to the sun.
And voila! This CD mobile now hangs right above the kids' bed, and they love it.
