You run a website that lets people upload videos. Some of the site's users upload clips that include songs. And some of the songs belong to copyright owners who don't like the idea of having people hear their tunes for free.
Blawgletter knows just how you feel. We also know the question you itch to ask us. Do you owe money to the copyright owners?
Under the "safe harbor" part of the Digital Millennium Copyright Act of 2000, you may not. See UMG Recordings, Inc. v. Shelter Capital Partners LLC, No. 09-55902 (9th Cir. Dec. 22, 2011).
