[The Sixth Rat Packer]

I was meaning more along the lines of them being able to analyze the MP3 and being able to tell whether it was from a retail disc or if it was something else.

As I type that I feel like an idiot because it sounds stupid, but I always wondered why someone couldn't just say "these are all my own backups, but I lost the physical cds. Good thing I backed them up, eh?" lol
