Public music-rights transaction data supporting 'Betting on the Known: Platform Economics, Familiarity, and Cultural Allocation'

CORRECTED MUSIC-RIGHTS TRANSACTION DATASET — RELEASE NOTES This release corrects and documents the transaction-level music-rights data used in Betting on the Known: Platform Economics, Familiarity, and Cultural Allocation. It retains the nine records and identifiers from the supplied transaction CSV: seven selected 2023 acquisition-related records and two later securitisations. It is not an annual market census. Changes- Added buyers and clarified the assets acquired or financed where supported by the cited sources.- Added attributed media/industry estimates for the Bieber and Perry transactions, and the announced Round Hill equity-offer valuation. These are not uniformly confirmed final transaction prices.- Corrected the Paul Simon entry to identify royalty income streams from Simon & Garfunkel recordings, distinct from the earlier publishing-catalogue sale.- Distinguished reports that explicitly say a price was undisclosed from reports that do not state a price.- Kept securitisation issuance amounts and collateral valuations separate from acquisition spending, and marked reported greater-than quantities as strict lower bounds.- Added a field-level correction log and a data dictionary, and preserved the supplied original transaction file for comparison.- Retained the supplied annual benchmark and retrieval-log files unchanged; they were not reverified as part of transaction cleaning.- Replaced the main README and data dictionary with versions covering all three original data files and the correction log; retained the supplied original documentation unchanged in a clearly labelled archive.- Did not add the 131-deal count mentioned in the original README: the supplied benchmark CSV has a blank count and the prior source audit could not verify it. The records are selected public reports, not a complete market total. Estimates, equity valuations, financing amounts and collateral valuations measure different quantities. The original retrieval date remains a historical log entry; later verification does not reconstruct the original searches. See the data dictionary and correction log for field definitions, individual sources and the detailed change history.
