You’re off topic.
I’m sure there already are plenty of similar topics.
Please use one of them or create a topic next time, because it’s a specific case completely on MusicBrainz topic related to adding digital releases to MB.
And also this way I could have tagged the new or existing topic as digital-media, one of my muted tags.
Now, depending on the response rate to your post, I may have to mute this fun topic. 
It would be a pity.
