reciprocal agreements with 51 different collecting societies. A reciprocal agreement facilitates the mutual granting of rights; foreign collecting societies transfer to GEMA the exercise of performance, broadcast, and reproduction rights of their entire inventory within Germany, along with the collection of corresponding usage fees, and in return GEMA grants the same rights and duties to foreign counterparts holding corresponding legal positions in their own territories.

This is because, after the expiration of the original contract, YouTube and GEMA had not yet come to an agreement on a new contract (see section Blocking of YouTube videos in Germany below). On 2 April 2009, a lawsuit took place before the regional court of Munich, in which the plaintiff, German singer , demanded a court-backed disclosure of GEMA's business practices. According her own statements, Clear paid a total of €80,000 in fees for her concerts between 2004 and 2007 and received around €10,000 in payouts, despite more than half of the performed music being composed, texted, and performed by herself. By her own calculations, she expected a return of approximately €33,000. The verdict, made
