Strangely by coincidence, I've just discovered to my amusement what you have been describing in this video about bots which automatically detect if a YouTube video is a portrayal of a composition which has copyright protection.

Just for a bit of fun, I uploaded a video of me playing (not singing) "I Don't Like Mondays" on the piano onto YouTube. In spite of the fact it's only had 10 views, it has been served with a copyright notice covering all territories - well thanks Bob! I can only assume that either my rendition was so close to Johnnie Fingers' original that it got picked up by a bot, or that somebody has dobbed me in!!

For my next project I plan to play Benny and Bjorn's world famous composition entitled "Money, Money, Money" - but shss, whatever you do, don't tell the publisher...

Interesting; my Day80 video diary which features my version of Dylan's Just Like A Woman has been Copyright Claimed by his publisher (quite right too); still my Babies On Razor Blades version of The Times They Are A'Changing still HASN'T been spotted.

Panic over; YouTune have said that the copyright claim is not a strike - BMG’ll just take any ad revenue, in the unlikely event my video becomes a hit.
