Hey, I'm afraid I don't know if my collection is complete. I started listening (by the looks of when my files were downloaded) in March of 2012, and kept listening until Sept 2012, which was I think when it wrapped up. My downloaded dates don't match up exactly with any of the dates in yours, so it's possible they are distinct.

I have added my download date to each of them, but they don't correspond to the release date. You can try and match up the ones you have, or if you make them available somewhere I'd be happy to listen myself in case there are any new ones there :)
