It may well be using the "music brainz artist id" rather than the "artists" tag, I did not dig that deep, it doesn't matter it is wrong and it doesn't work for me and it doesn't work for a lot of other people the logic of using that tag is unfathomable.

Having as flexible system that can use any tags and present the library via the myriad of possibilities that are presented by the tags would make sense.
