Every now and again I DJ at the National Portrait Gallery in London. There is only one song that I always play: Kraftwerk’s ‘Europe Endless’. Each time I play it the song takes on a different hue. I have played it in support of the Greek fight against the austerity programme, and last year I played at as the refugee crisis reached one of its peaks. It is a song that resonates with people. The melody is uplifting and it contains all the promise of a European union. The song is nine minutes long, but aside from the repeated title there are only a dozen or so words. They nevertheless say all you need to know about Europe’s grandeur and its facade: ‘parks, hotels and palaces, promenades and avenues, real life and postcard views, elegance and decadence’. Usually someone will come up to me and say ‘what is this?’, or they will probe me with their Shazam. The last time I played 'Europe Endless' things were different, however. It was only two weeks ago. For once, the song was ignored. People talked all over it and it couldn’t get itself heard. I guess this was a sign.
