Remember when copyright complaints from labels led to Apple and Google removing Grooveshark’s official mobile app from their stores? It looks like the same thing has happened with its Facebook sharing features. We reported yesterday on the disabling of Grooveshark’s Facebook features, and now the social network has confirmed that “We have removed the Grooveshark app due to a copyright infringement complaint we received”. Grooveshark had previously said that it believed the removal was an error, and would soon be rectified. Music rightsholders will cheer Facebook’s willingness to take action, but the move will be controversial – particularly if Grooveshark was given no opportunity to mount a defence before its app was removed.
