It is only these conversations that are teaching me what an “imprint” is. Before I would have just called it “Label” or “the company who are selling the product”.
This is you helping clarify to me exactly what an imprint is. Now I get it totally. Thanks. The following is my understanding of this whole thing.
EMI ownership will confuse anything due to their many profit layers, departments and many tax avoiding lawyers. The original 1970s-1990s Star Song are a simpler outfit.
This is why I usually focus on “copyright holder” and “label selling product”. When it comes to that 2009 EMI CD there are multiple names now involved on that rear cover as each chunk of the business is split up.
I think the “Star Song become Imprint” in 1998 is when EMI have taken a famous old company, and then just gobbled them up into their huge business, and turned them into just an imprint. Just a name and logo. Just a small little sub-section of their massive machine. No one works for them anymore as the company has ceased to be.
In that news article it seems to describe EMI taking famous names of classic labels and just making them “Imprints” of yet another EMI department.
EMI CMG is the Christian Music arm of EMI. It encompasses : “Sparrow, Forefront, Star Song, EMI Gospel, Worship Together and re:think records as well as EMI Christian Music Publishing and Cordant Distribution Group”
So before 1994 Star Song was it’s own company, trading under the name of Star Song Communications. Then 1994 EMI bought it, closed the company, and instead made an Imprint of it and just sucked it into the Beast that is EMI profit machine.
I would have a Label called Star Song Communications with an Alias of Star Song. They would be trading from 1974 to 1994. And then I would make a second Star Song from 1998 which is just an Imprint. It’s parent is EMI CMG. And the parent of EMI CMG is EMI.
I’d have to look at more examples to work out if the title of the 1974 Label should be “Star Song” or “Star Song Communications”. Whichever is the more common, and just set the other as the alias. I don’t think they are big enough to split.
I think that is the best I understand of it. And I’ll be honest, this is the side of music I don’t really like. Seeing a big Beast like EMI making profits out of someone else’s work. But I don’t want this to turn into a rant against record labels before I have had my morning coffee 
Edited to add: I have now read beyond the first two paragraphs. This article is basically EMI’s obituary for Star Song. They bought it in 1994, moved it into an office with other religious labels they have bought (Sparrow) and by 1998 gave up pretending to run the label and just merged everything into a single entity.
The only puzzle to me is the end date of Star Song. Is that 1994 when bought by EMI, or 1998 when EMI killed it as a separate entity.
