Music Week reports that the UK Parliamentary inquiry into the economics of streaming and how labels share royalties with artists has sparked a war of words between Spotify and Apple Music. The article by Andre Paine cites Apple Music's response to Spotify's March launch of a website as part of its pledge to show greater transparency on streaming royalties. In its turn, Apple Music claims it pays streaming royalties of one cent per stream, as opposed to Spotify's rate of one third to half a cent per stream, according to a letter to artists, labels and publishers seen by the Wall Street Journal. Spotify dominates the market with 155 million paid subscribers in late 2020, while Apple Music had 60 million subscribers in 2019.
