To nitpick your nitpick: there were many attempts to implement DRM even on pure music CDs, see https://en.wikipedia.org/wiki/Copy_Control My personal experience with this was with some import CDs (from Japan) that, from what I recall, messed with the error correction part of the data so that it skipped horrendously in my PC (so it was impossible to rip in cdex) but played fine in (most) standalone audio players. |

"As the Copy Control discs do not conform to the requirements of the CD standard, they are not labeled with the CDDA logo, which is trademarked by Philips."
