So when amateur vids of Led Zeppelin’s reunion concert started disappearing from YouTube and were replaced by a message stating that the content was removed “due to a copyright claim by Warner Music Group,” it wasn’t all that surprising.

Except that Warner wasn’t involved with the removal of Zeppelin clips. And neither was the band.

Instead, that dubious honor goes to third-party copyright infringement fighter Grayzone, according to Silicon Alley Insider, which posted the following statement issued by the company:

“Grayzone regrets that it erroneously issued takedown notices to YouTube regarding footage of Led Zeppelin’s December 10th concert. The error is ours alone. We acted without authorization from the band or Warner Music Group. Unfortunately, an automated system mistakenly attributed the removal of the content to a copyright claim by Warner Music Group. That was inaccurate. We have informed YouTube of the error and we regret any inconvenience this may have caused.”

You gotta love that line about “an automated system mistakenly attributed the removal …” As far as we know, human beings are still the only species on the planet, carbon-based or otherwise, capable of making mistakes. And systems, even automated ones, only do what their human overlords tell them.
