After more than a year of negotiations, talks between YouTube and a German group that represents musicians have broken down.  The group, GEMA, has demanded that YouTube block access to around 600 videos as a result, and hinted that other agencies could soon echo its call, too.

German users of YouTube have, like the rest of us, been subjected to the upside-down display prank Google scheduled for April 1st.  Unfortunately for them, music videos have also been pulled from the German version of the site, and this move looks to be serious and long-lasting.
