DRM
Buying CDs is wasteful for me… I don’t need to have Amazon send me a plastic discs in plastic cases with plastic stickers wrapped in cardboard boxes, shipped to me on trucks and dropped off in my office by those delivery guys who listen to loud rap music and use their push-to-talk phones in the elevator, just so I can rip the disc into iTunes and never touch it again.
But if it comes down to buying a CD or buying DRM tracks, DRM loses. Every time.
