Hello “Dimension 8” 
Juan here, from our Product Team.
First of all, congratulations on your release! Me being from Rio might be a bit biased opinion, but nice one!
Regarding Amazon links, it is something we have been struggling to get right for everybody because Amazon is quite special on the way they handle their shop links, either the redirects to the different shops, aka “amazon.com”, “amazon.de”, “amazon.fr”, and to the music service directly, aka “music.amazon.com”, “music.amazon.fr” , “music.amazon.fr”,…
Our link fetching service scans for the album/release using different parameters, according to the shop we’re trying to find, and for Amazon we mostly use the “Release Title” and “Artist name”. Then, as soon as a link is located that matches those parameters, we use it and we would expect Amazon to redirect to the shop the customer needs to visit. We’ve made tests in the past, forcing the system to use the “.com” links, but they were not as succesful as one might think. Many people do not distribute on the US, for legal reasons, and those “.com” links are not “universal”, but related to the US shops, and this would result in a broken page.
That being said, for this specific release, we believe could be a better solution to redirect to https://music.amazon.de/albums/B0FGY78DXH instead of https://www.amazon.de/dp/B0FGY9V9NS, as currently your Release Page has.
I have raised this concern with our backend developers, who are in charge of such decisions but in the meantime, I’ve regenerated mysef your page, to include it. That should make things better.
Feel free to give your feedback after this change.
Have a great day!
Best Regards,
Juan
