Laurel the lawyer

Laurel pointed out something I honestly hadn't considered (or at least hadn't chosen to remember): If you sell your CDs (or trade them for goods), that means you no longer own the right to the ripped version of the CD. So, I could trade all of our CDs for an iPod, but I'd have to erase the MP3s from my computer, meaning that I'd have no need for a 60-gig iPod anymore.

I was just bored enough during the break that if this had come up earlier, I probably would have taken the time to organize my audio file collection by original source, so I could easily see how much of my collection would be lost in this transaction, but a rough guess is maybe 75%.
