When I was in Germany several years ago, I attempted to play a music video on YouTube that I had first seen in the United Kingdom. It was blocked on copyright grounds. I wondered, if the European Union guarantees the free movement of goods and services between Member States (which the UK and Germany both are), how could Germany block access to music I could freely access back home in London? This question inspired my Masters Thesis, which explored European copyright law in the context of digital music services. I even got to interview the head of licencing at Spotify as part of my research!
