This article explores the key standards identified by songwriters, collaborative artists, and music industry representatives in the commercial pop and Schlager sectors, along with the platform-centric myths they implicitly address. We first provide a theoretical overview of collaborative songwriting and platformisation. Through original interviews and ethnographic observations, we examine two primary platform standards: streaming and social media. We emphasise the growing significance of collaborative songwriting in the streaming era, particularly through songwriting camps, and the pervasive use of social media in creative and economic contexts. Our analysis demystifies two prevalent myths. The first myth concerns the ambiguous role of intermediaries, especially publishers, who act as new service points for efficient billing and songwriting facilitation. The second myth addresses TikTok's success and its declining conversion rates for streaming.
