Thanks, but it looks a CD that you receive by mail. Not a download. There definitely aren't any tracks to download.
That's not a CD... :-)
It's all the items in the box set, in digital file format on a USB drive.
The digital music files are in FLAC format, plus MP3 (if I read that right). It also has the movies on it, too, plus pictures and booklets. And, once you have that, you can move it around "digitally" to any machine or transfer it anywhere you want (iPod, iPhone, laptop, desktop, etc...).
That's about the closest thing you're gonna come to it being "digital"... (for right now, anyway).
The USB drive is the last item on the right... :-)
