I came accross this while dumping my collection of audio CDs. I'm trying to dump them completely, including scanning booklets and also saving any bonus material on data tracks that some disks have.
One such disk is the Tron Legacy soundtrack by Daft Punk. It has a data track on the CD, unfortunately, all it contains is an executable file that just opens a website (that's now offline).
But the bonus content that used to be there is behind a login wall, and so the web archive didn't keep a copy. In the end, all that's left is this static image from the login wall on the website:
The videos don't seem very hard to find (they are just 3 movie trailers and the video clip for one of the songs, I doubt these are lost?). But I am curious about the "gallery" part and the pictures that were there. Probably nothing extremely interesting there either, but, I would like my CD archiving to be as complete as possible.
