A simple method may be to use something such as 'SuperMP3Recorder' that effectivley records what comes out of your sound card to an MP3 or WAV format.. Since its not a Mic recording and its digitally direct the quality isn't deterriorated too much.
If you can play it, you can copy it!!
OR: Burn to CD then re-rip from the CD.. maybe faster if you have 12hours of music to copy!!!
