Probably a typo.
Or, you could just have your radio reciever running through your cassete player, and then press the "record" button.
But not only does that not apply to the idea of CD's using for piracy, but it also doesn't give you access to the songs in MP3 format.
Oh, I had thought you were giving me an alternative to an old technique, not commenting on the ways to do it now.
Any how, I think there should be a $0.10 tax per disk on blank CDs, that way the RIAA can eat shit.
