That is why it has always been its own game.
I had pretty much given up on DLC with nothing new coming in a year, but the sale announcement pretty much was the official death knell on Beatles DLC (at least IMO). It was great that we got the stuff that we did, but I was hoping we would at least see a little bit more for a Beatles game.
As for the forum, I'd long given up on that. I've been seeing "Beatles album game" and "song survivor" stuff on forums for so long, it has been incredibly played out over the last decade plus.
