I’ve never seen a different release with the same barcode with different mastering. To me it’s not any different than playing an audiophile 180g record on a bad record player. It’s not the releases fault, just the technology that delivers it. It’s no more apparent than the fact that Apple just all of a sudden turned millions of their 16 bit releases into 24 bit releases over night. Because they already had the release, they just updated their software to play it. Many times I go to a release on a “hi-res” site, they offer the same release in different formats and you can just pick the one you want. Same ID, Same barcode, etc. Do you want to add the different ones as different releases, even though they have the same barcode and link, etc. It does appear that the sites are getting better at it though. Also, iTunes now has hi-res lossless on many of their releases. You wouldn’t know this without loading it in the app or looking at the “view-source” data on a page. They don’t advertise it on the release pages. They will be added as the same release as Spotify and Deezer and have been by the 1000s by a-tisket, because an average editor wouldn’t even know they were different. Honestly, I haven’t seen people separating them out for a few years until very recently. Of course, if there is anything different on a release it can be a separate release, I just fail to see how 16 bit or 24 bit, etc. is enough to say it’s a different release, when it’s only the limitations of the site that are the issue. I’ve changed on merging them, but unless I can figure out a clear difference by comparing the data, I don’t think we should ask people to separate out that hi-res Apple Music file from that CD quality Deezer link if everything else is the same. Mainly because when I stream them, it’s only CD quality because I’m not spending the money for hi-res lossless. It’s still the same release. I’m able to play it. It just doesn’t sound as good as it’s full potential.
