Unfortunately, profit has to come first for every company. That's just a reality. No business can afford to throw out product after product with no care over whether or not said products make a solid return profit. That's why artists are continually dropped from record labels and movies aren't given sequels.
Yeah, while I would love for the focus to be on the art itself, financials have to be considered. Although I think there should always be a balance, they're never going to make as much money as a modern artist's album and that should be expected.
I don't expect every MJ product to reach the Top Ten in many markets, and there will eventually be a period where Michael isn't hitting the numbers he did with Michael/Xscape. While I'm not an expert on the subject, I don't imagine every product would need to be Top Ten hits around the globe for it to make money. My thinking goes to other artists who put out these nice packages for re-issued albums that don't even make the Top 10, hell maybe not even the Top 20-40.
In addition, just because Elvis couldn't posthumously pull it off, doesn't mean Michael can't. After all unlike Michael, Elvis hasn't really had that great numbers in the US for the past decade anyway: His last Top 10 album was
2nd To None back in 2003, 2008's Christmas Duet's reached #17, 2010's Viva Elvis didn't even chart, 2015's
If I Can Dream (the first Elvis orchestral album) reached #21 and this one reached #47. I mean, they're fine for Elvis as he's not a big modern artist anymore but Michael could do better.
I wouldn't mind if they did a similar album for Michael, they could have some tracks based on his actual compositions that was discussed a few posts up, then do adaptations of his hits similar to those Elvis albums. I think what I would really love though is that MTV Unplugged kinda album though, I really like the acoustic demo of SOOML!
