i'm not really worried... there are so many loopholes that i'll find a way to make it happen. i'm not going to upload them here, so they'll just have to delete my threads (the mods are pretty good at that), links i post, and links i put in my profile.
furthermore, so much of the stuff i've been listening to recently isn't available in the US (Axwell, Guetta, etc) and the artists are VERY understanding about copyright issues... i might have trouble keeping it up on NS, but i know i'll never have any issues with the artists or their labels. these guys want their music out there- they don't get too hung-up on copyright bullshit. the point is to spread the music, not be a bitch about it.
bottom line, i'm not worried about it at all.
