The current iTunes album ID for the album “No More Drama (Version 1)” is 1440817211. a-tisket returns UPC 602547111470 for it. This UPC does not correspond with the UPC of the release in MB, which otherwise represents this digital release exactly (with occasional 1-second track duration differences though).
Btw, Apple has been changing the album ID numbers over time, and as you can check, the old iTunes Store link on the MB release page will be redirected to the current album ID.
So, I am thinking I should edit the release and update the UPC and update the iTunes Store link. But first, I would like to know from you @marlonob please:
Why do you think the barcode might be different? This album has been available from iTunes at least since 2007. Why would they change the barcode?
I am asking because I would like to have some reassurance that a-tisket uses up-to-date data sources and the correct data source. Reading iTunes UPC Database, I got the impression that it might depend on the copy of a database. How sure are you that the UPC is correct?
I can see in the editing history, that the release was added by @a23bed 2 years ago with a script. That too might be a source of error, and there is no information how this script obtains the UPC…
