As much as I absolutely loathe Sony, it turns out Sony/BMG is allowing use of Rick Astley's "Never Gonna Give You Up."
In Episode 691 of Buzz Out Loud (a great podcast, by the way), a story is told about someone who posted a video of his grandkids on YouTube with the purpose of Rickrolling his family members. He got a copyright violation notice from YouTube. In this form letter, it lists the owner of the copyright, and it explains that if the word "approve" appears after the copyright owner's name, the video may stay up. The letter listed Sony/BMG, after which was listed "approved for all use".
("Rickrolling" is an Internet meme in which someone gives out a seemingly important or relevant link which instead directs the victim to a video of Rick Astley's "Never Gonna Give You Up.)
Congratulations! You may now Rickroll without consequence! Well, at least not from Sony...
