Music CDs...I have a bunch. What can I do with them?

[Joey Cupcakes]

Yeah, there's a special code in them that is required by stand alone CD Audio recorders- the surcharge on them is supposed to offset record label's losses for audio CD piracy (though I, as a working musician, can't say I know of a single musician who's ever benefitted from it...)

But once you get past that code, they are just standard data CD-Rs.
