Bag of CDs

I've been using computers for about 8 years now and I have a bag of 5 CDs that i can stamp as defiantly obsolete. That's not much you would probably say but it looks like its going to start to rise in number as I switch to Vista as a heap of very old games won't work, old driver CDs for dead printers and scanners etc. but what to do with them?

I've seen websites with donate your CDs to them kind of things but I really don't trust ppl with my burnt CDs, don't mind the ones i brought but don't know what they can do with my old music compilations etc.

Still looking for recycling methods, care to suggest?
