Are Soundcloud tracks official or promotional releases?

so basically any release of a single (that later would be included in album) can be marked as promo with this discripton.
and Noisia doesn’t even falls under “give-away release” bc it requaires payed subscription.

Yes, bc nobody voted against that, Xythium just put “old promo” in the descripton. And there is basically no way to verify official or promo status of (for example) that Anmon release
let’s say i will make an edit of this release and mark it as official, there is no way to be shure who is right.

in my edits i was I was guided by text of the guidelines, and distinct features of physical promo releases which distinguishes an official release from a promo

There should be a way to differentiate digital official releases from digital promo releases. In my eyes distinctive features of physycal promo releases are applicable to digital ones.

the wording of this guideline has been confusing for many users (including myself early on), but this has not been the community consensus or general practice. I’ve actually started a discussion on changing the wording here to make it clearer (as well as some of the other points you’ve raised here)

these do fall under the second use case, namely it’s “a release intended to promote an upcoming official release”, such as The Resonance I, which was released a few days early on Patreon
