Why are there two extra discs?

LCD R - Mac Sync (Pop Craze) [Alternate Packaging] First disc with same contents as the original packaging.

I don't really remember the story to this one. Two discs stacked in the tray, one under. One copy made


Everything Same contents as original packaging


DVDr 2:

Oh, this is where I put that. I had downloaded all of the Aphex Twin tracks put on his soundcloud at one point. At some other point I put them on this disc. I don't know why it's in here.


Hidden DVDr:

This is the bonus album that's mentioned on the original packaging. I also don't want to list it here.
