This working paper explores the analytical possibilities opened by platform- and distributor-level streaming data for music market analysis. Using a fictitious sound recording and simulated contractual conditions, the paper demonstrates how detailed reporting can be used to reconstruct prices, quantities, and revenues across streaming platforms, subscription tiers, and territories. The analysis focuses on methodological transparency rather than empirical claims, and all data are either synthetic or anonymised. The paper is motivated by the limitations of publicly available national and international market reports, which typically aggregate revenues without distinguishing domestic and foreign earnings or platform-specific price–quantity dynamics. By contrast, distributor-level reporting can, in principle, support the separation of territorial revenues, the identification of effective unit prices, and the alignment of consumption volumes with remuneration outcomes. This preprint is intended as a methodological exploration and proof of concept. It does not present representative market results and does not rely on confidential commercial data. Instead, it illustrates how greater transparency could enhance economic analysis, policy evaluation, and regulatory dialogue in digital music markets. The paper is released as a working document to support ongoing research and discussion.
