Spotify, Pandora and others have effectively offered music on demand, anywhere, anytime, any device and in doing so have offered both discoverability and convenience at an affordable subscription. This concept changes ownership, rights, valuation and the business model that the relatively new music business has operated within from its conception. iTunes reintroduced the single track, but often at a cost that made little sense to the collector or for people who want to discover new artists and then immerse themselves in their work. 'All you can eat' subscription offers enable the consumer to experiment, take risk and enjoy a wider range of artists than the buy through model. So do the subscription members now listen to more or less music?
