You might have already heard of it — the new Nine Inch Nails album "The Slip" has been released by them under the Creative Commons BY-NC-SA 3.0 US license. Yep, that's right, it's totally legal to download it from the web — and use it for any non-commercial purposes!
It's a bit annoying that they want your email address, though. Nothing that bugmenot.com (or similar) cannot fix, but still. Luckily, the files are now also available from archive.org! This, and the fact that the music is CC-licensed allowed me to "play" one of the songs in my Creative Commons music podcast (RSS), and more will likely follow.
