[Gartner.com] What makes the Sony BMG incident even more unfortunate is that the DRM technology can be defeated easily. Gartner has identified one simple technique: The user simply applies a fingernail-sized piece of opaque tape to the outer edge of the disc, rendering session 2 – which contains the self-loading DRM software – unreadable. The PC then treats the CD as an ordinary single-session music CD, and the commonly used CD "rip" programs continue to work as usual.

I love it – DRM defeated by Scotch tape. Ha.
