This is why copyright is dumb and doesn't translate properly to cyberspace. There is no way in hell the RIAA would bring a case against you for listening to a record that you own in the privacy of your home with a group of your friends. This is the exact cyberspace equivalent to this meatspace activity, which is obviously entirely legal and desirable and socially acceptable. The fact that we can't have nice things over a technicality that there's some distance involved and computers is utterly insane.
