Candice G: How do you de-authorize a computer from itunes when you no longer have that computer?
I have some songs that I can’t add to my new ipod because it’s been authorized by 5 computers. We no longer have any of those computers and I need to de-authorize those old computer so I can authorize it on my new computer.

you would need to find those computers and deactivate the itunes. if you can’t contact apple, there might be something they can do, but it seems unlikely.
