Digital service providers (DSPs) have copped a lot of flack for a perceived lack of support for classical music. Some of the criticism has been leveled at the methodologies used to ingest and display classical, which can vary widely from store to store. A universal standard amongst stores for organising classical music would be ideal. However, this is half the problem; for DSPs to ever display classical metadata correctly, they’ll always be reliant on a supply of consistently good metadata.
One solution is to supply classical content in a way that’s homogenous with the way the same content is managed by the digital services that invest the most in it. iTunes, in particular, has an established methodology for classical metadata, which encompasses many millions of albums and tracks. Their conventions therefore heavily influence how we should supply our metadata. Or to put it another way, do as the store demands consistently, or don’t see it on store.
