What is ‘the Core’ exactly, or where are the data it contains coming from?
If it consists of the data of all customers in your cloud, it should really have a supervisor to check every contribution. Almost every CD I add to ‘my’ collection, is not found, or the data is very incomplete, or partly or completely wrong.
Why are the data incomplete when an album is found? Why are the tracks wrongly mentioned, or not mentioned at all? Why is it so hard to have correct track lists in a multi-disc album?
It seems to me there is no point in storing incomplete or erroneous data in a database, is there?
