Everyone listens to music – streamed, on the radio or at a live concert. But hardly anyone knows what happens behind the scenes in the glittering music world. The documentary series reveals small and big secrets. She tells stories of influential investors and their tricks to increase money and power; and by artists who dare to speak out about injustices. They sit down at the table for the first time: Balbina, Maeckes, Chefket, Rocko Schamoni, Peter Maffay and others talk openly about how little they earn from streaming. The band OK Kid gives exclusive insight into their work. Investigative reporters are looking for so-called ghost musicians who dominate some Spotify playlists. And then there is Smudo, musician with the Fantastischen Vier, who, as a businessman, has taken on one of the biggest players in the music industry.
