Although the ASIN for a physical release appears to be the same on Amazon sites for different countries, this is not the case for a digital release (or should we say “releases”?). Each Amazon site has a different ASIN, usually with a different label and release date:
Germany: https://www.amazon.de/gp/product/B004ITS862, label “Decca”, release date February 18, 2011
France: https://www.amazon.fr/gp/product/B00AO6CGXE, label “Universal Music Division Classics Jazz”, release date September 1, 2012
Italy: https://www.amazon.it/gp/product/B009AMH8CW, label “Universal Music Italia srL.”, release date November 2, 2010
Spain: https://www.amazon.es/gp/product/B009IJM6CO, label “Universal Music Spain S.L.”, release date November 2, 2010
UK: https://www.amazon.co.uk/gp/product/B0046OFJN4, label “Decca (UMO)”, release date November 2, 2010
US: https://www.amazon.com/gp/product/B0051U6JWC, label “Decca”, release date May 31, 2011
It looks like if one wants to be absolutely precise, many separate digital releases are required, one for each Amazon site.
