💾 Our takeaway:

Editorial curation still shows a "popularity bias", making it difficult for new artists to break through and increasing barriers to entry.

It raises regulatory questions regarding market concentration and cultural diversity in the recorded music industry 🎶

However, established artists start with more listeners on average, so the same proportional boost means much higher absolute gains (in both streams and revenue).

Using an event-study design (robust to staggered adoption), we estimate how streams change before and after playlist inclusion or drop.

Both groups see similar percentage gains (resulting from inclusion) and losses (resulting from drop).

When emerging artists do make it onto playlists, they’re typically:

• Placed lower in the track order
• Featured on less popular playlists
• Removed sooner than established artists

We define emerging artists as those with <2 years of career seniority.

Across all curators in France (Spotify + Major Labels), their share of playlisted tracks has declined since 2021.

💡Key findings:

• Emerging artists’ presence in editorial playlists is declining over time
• When featured, they get less visibility (lower rank, shorter stays)
• Playlist inclusion boosts streams similarly for everyone (in proportion)...
• ...but established artists win much more in absolute terms

Des décennies de sévices, de silence et de déni sur Bétharram, et le problème pour la ministre de l’Éducation nationale, c’est… Mediapart.

Réalise-t-elle qu’elle ne fait que prolonger le problème en réagissant de la sorte ?

Je fais partie des ceux qui ont alerté sur le risque fasciste du trumpisme. On nous a reproché d’être politiquement orientés, « d’exagérer ».
Là ça fait des saluts nazis, ça parle d’envahir des pays et de déporter des populations.
C’est bon ? On peut parler de fascisme ou c’est encore trop peu ?

Je savais que Cyberpunk 2077 s'inspirait d'un JDR appelé Cyberpunk 2020 mais je ne connaissais que Netrunner (incroyable jeu de cartes) dans cet univers. Mais là je viens de découvrir les couvertures des livres pour maître de jeu ! C'est dommage qu'ils aient perdu ce côté grim dark dans l'adaptation

On peut prédire les effets:

- une privatisation de la prise en charge, sans gain de pouvoir d'achat en moyenne pour les assurés

- un effet inégalitaire (la sécu a un financement proportionnel au revenu, les comp non)

- hausse des obstacles/renoncement au soin pour les moins couverts

...a beneficial effect for the regulator, who could use this lever to promote cultural diversity (via the discovery of new tracks through demand); but a more contrasting effect for platforms depending on their royalties distribution system (“market-centric” vs. “user-centric”)

✅ Similar effects can be found in terms of feedback on the recommended tracks: higher like rate, lesser dislike rate, etc.

This effect is persistent during the firsts 30 tracks, then it decreases to reach the level of the other groups

Key findings 💡: When explanations are provided, users spend more time listening to music tracks than "browsing" (i.e. skipping between the tracks before actually listening), but if and only if people get involved in the explanation (spending a significant time reading to it and understanding it)
