Amazon offers many old CDs as streams or mp3 for purchase. Does it qualifies for a separate digital release?
Let’s take an example. A CD was released in 1991, and it is still sold on Amazon as a physical media: https://www.amazon.com/gp/product/B01KAU19YU
The same music is also sold on Amazon as streaming or as mp3 downloads with a different ASIN: https://www.amazon.com/gp/product/B0051U6JWC
What is the current policy: should we consider the streaming / mp3 to be a separate digital release?
If a separate digital release is in order, what is the release label for a digital release in such case: is it still the original label which released the CD in 1991, or is it Amazon? A similar question for the release date: is it the same for the digital release as for the original CD (1991), or is it the date when streaming of this CD was offered by Amazon?
