outsourcing data-entry
Not only are there missing albums, but Xperi's data is also becoming more and more incomplete for albums that its editors aren't reviewing. For many of these albums, Xperi has decided to skip data-entry of track listings or credits or composers. If Xperi is earning more from its customers, the customers are getting less data in return.
I think that Xperi would be happy to reduce its workload for data-entry to only albums that its editors are reviewing. By reducing its workload this way, Xperi would cut its operating costs. I also think that Xperi would be willing to pay part of the saving from cost-cutting to a data vendor in order to license the vendor's data (for which Xperi no longer needs to perform data-entry) because Xperi can resell that licensed data to its own customers. I presume that Xperi would ultimately pass on any net saving to its customers by equivalently reducing the amount that it's charging customers.
