This is not a complete list and
Sony-BMG continues to refuse to make such a list available to consumers. Consumers can spot CDs with XCP by inspecting a CD closely, checking the left transparent spine on the front of the case for a label that says "CONTENT PROTECTED." The back of these CDs also mention XCP in fine print. You can find pictures of these and other telltale labeling at http://www.eff.org/IP/DRM/Sony-BMG/.
