[quote name='Naterrs']Not that I condone piracy, but is there any difference between downloading music illegally and buying a used CD from someone on eBay? You're not supporting the original artist or recording label when you buy used, but it's not illegal. Just offering an argument I didn't really think about for too long XD Anyway, this is neat. Already got a few of the $5 albums they're offering through the video game purchases I've made including one Gamecube controller, though I thought it was limited to actual games[/QUOTE]
Here is why buying used is legal. When you buy a CD, you're really buying a license to listen to that music; the CD is merely a way to get the music to you. As long as you have it in your possession, you hold the "deed", so to speak.
When you sell it, you're passing it on to someone else, and LEGALLY SPEAKING you're not supposed to listen to it anymore. That includes any mp3 rips or whatever you may have done. The demand from one customer has been filled while at the same time you are now deprived and demand has been created again (assuming it's a good album that you'll want to listen to again someday). You could still argue that you "stole" a potential real sale, but that's the idea.
The other day at work, someone was actually trying to tell me that "burn and return" (or in this case "burn and trade in") is perfectly legal and morally sound. If this person had been 16 years old, I could've understood because kids growing up now have a skewed sense of what copyright is, but this person is 45!
