A new version of the retroharmonize R package — which is working with retrospective, ex post harmonization of survey data — was released yesterday after peer-review on CRAN. It allows us to compare opinion polling data from the Arab Barometer with the Eurobarometer and Afrorbarometer. This is the first version that is released in the rOpenGov community, a community of R package developers on open government data analytics and related topics.

Surveys are the most important data sources in social and economic statistics — they ask people about their lives, their attitudes and self-reported actions, or record data from companies…


The idea of our Digital Music Observatory was brought to the UK policy debate on music streaming by the Written evidence submitted by The state51 Music Group to the Economics of music streaming review of the UK Parliaments’ DCMS Committee.

The music industry requires a permanent market monitoring facility to win fights in competition tribunals, because it is increasingly disputing revenues with the world’s biggest data owners. This was precisely the role of the former CEEMID program, which was initiated by a group of collective management societies. Starting with three relatively data-poor countries, where data pooling allowed rightsholders to increase…


We do care what our children learn, but we do not care yet about what our robots learn from. One key idea behind trustworthy AI is that you verify what data sources your machine learning algorithms can learn from. As we have emphasised in our forthcoming academic paper and in our experiments, one key problem that goes wrong when you see too few small country artists, or too few womxn in the charts is that the big tech recommendation systems and other autonomous systems are learning from historically biased or patchy data.

This is precisely the type of work we are doing with the continued support of the Slovak national rightsholder organizations. In our work in Slovakia, we reverse engineered some of these undesirable outcomes. Our Slovak musicologist data curator, Dominika Semaňáková explains how we want to teach machine learning algorithms to learn more about Slovak music in her introductory interview.

A key mission of our Digital Music Observatory


Traitors in a war used to be executed by firing squad, and it was a psychologically burdensome task for soldiers to have to shoot former comrades. When a 10-marksman squad fired 8 blank and 2 live ammunition, the traitor would be 100% dead, and the soldiers firing would walk away with a semblance of consolation in the fact they had an 80% chance of not having been the one that killed a former comrade. This is a textbook example of assigning responsibility and blame in systems. …

Willemijn de Krey is a Dutch painter, musician, and occasional filmmaker living in Antwerp, Belgium.

Willemijn graduated from art academy ArtEZ in Enschede in 2011. At her final exhibition she was one of ten talented upcoming artists across the graduates of the three ArtEZ art academies selected to show their work at Oostenwind 11 in the Delta Lloyd building in Amsterdam. She moved to Antwerp to work in solitude and to find her creative environment. Besides making her own art, Willemijn also works as a painter on commission, as a production manager at Picoux Productions, and has been a vocalist…


An interesting meme is going around on social media that shows the gender specific translations created by Google Translate from a source text typed in a genderless language, Hungarian.

I was able to replicate this problem in several languages — English, Dutch, French, and German — and I am quite certain that the list could grow. What is going on here?


Flower of Sound invites you to become more calm, inspired, energized or focused. Let the stress flow away and elevate your own frequency. Claudio is a fellow in the JUMP European Music Accelerator Program with a particularly interesting Milano and Amersfoort based startup, Flower of Sound. I visited him and his co-founder, Elise,in Seats2meet Amersfoort CS. I found their approach particularly interesting because the model of music streaming is already being overtaken by informative radio-style programming in the form of podcasts and, next to that, all sorts of functional sounds that help people to meditate, drown out noise in a…


HAJDE is a digital platform specializing in eco-responsible and cultural tourism in Eastern Europe. Its founder, Thibaut Boudaud, is developing his project alongside our music observatory in the JUMP European Music Market Accelerator. I spoke with him on a video platform.

His first memories about the region are connected to his father, who served in the French zone of divided Berlin. Thibaut started to travel the region in 2008, starting with a memorable visit with Hungary’s Sziget Festival, then going further to Romania and Croatia. He has kept going back ever since: he has already visited 10 festivals in the…


After a couple of months on planing, the IASPM event I organised on the impacts of Covid-19 on the European Music Industries took place yesterday. The event featured six speakers, from Wales, England, Germany, Norway and the Netherlands. This work builds on the previous work I have posted concerning the situation in Wales — which you can access here and here.

There was some fascinating discussion that took place both during and after the presentations, which you can now see via the recording below. For me, I think the one noticeable factor was how much all of our nations had…


Gina Perier is a fellow in the JUMP European Music Market Accelerator. She is an architect trying to solve a serious problem before music festivals reopen after the pandemic: many, many women, all in one place… who need to pee.

What is your personal connection to music and festivals?

First of all, I like going to festivals, partying and listening to the concerts. Then, I used to work as an architect for Roskilde Festival in Denmark, together with my co-founder Alexander. For us, it was a great opportunity to observe the impact of our design on the festival and on…
