Music Labels to launch CMX, a new digital album format.

I later bought The Slip's physical release - the CD came with a DVD with rehearsal videos of nearly every song on the album. (it also came with... stickers!)
I'm betting the revenue from both of those legally-free-to-download releases will be more than all the profit made from sales of CMX-format albums combined.
edit: (totally off topic, but i can't wait to see them in NY the 25th. NIN is my favorite band. Saw LiTS tour four times last year.)
We call it... CD-ROM.
If one were to create such a standardized bundling format I can't imagine spending more than a day developing it. The bundle itself should be something simple like a ZIP file with a different extension. The audio files could be MP3. The artwork could be PDF.
But they didn't develop it: they almost certainly hired some IT consulting firm who billed them six or seven figures and spent months (or years) coming up with this ground-breaking innovation.
Wait...
... oh, wait. Carry on.
