Two years ago, Google removed Grooveshark’s Android app from Play.
Two hours ago, Google erased Grooveshark completely from its Chromecast partner list.
The Play removal was rumored to be the direct result of a demand from the major labels, spearheaded by Universal Music Group (which is leading a lawsuit against Grooveshark for massive copyright infringement). This time, the rumor is about the same, even though Grooveshark is actively defending itself against Universal Music Group and the major labels in court. A decision has yet to be rendered in those legal battles.
“After a jointly approved press release from Grooveshark, we were notified by Google [that] our app was suspended for Terms of Service of compliance.”
