When it comes to DMCA takedowns, Grooveshark is generally a company that likes to receive. But now, it turns out they also give on occasion.
Grooveshark (through parent Escape Media Group) appears to have sent this DMCA takedown notice to developers using their source code illegally. Grooveshark didn’t respond to the email listed on this takedown notice, which was posted on github (an inquiry was also sent to Grooveshark CEO Sam Tarantino.)
And, this would be the familiar result.
