Extreme CSPC: Introducing the ASR, Artist Success Rating


Have you ever thought that album sales of your favorite artist weren’t reflective of his real success or that a release from his label was unnecessary? All of us already wondered What if…? and felt bothered because there was no way to know what would have happened if things had been done differently. Here comes some serious food for thought that may help you find answers!

For two years now we have been studying carefully records’ sales of various major artists. I reassure you: we won’t stop doing it. Nor we will change the methodology. This article will present you a sharp concept that may turn you off, but give it a chance as it is mind-blowing. It will come as a complement of the CSPC approach rather than as a replacement. For the first time, we will tell you that 1 isn’t always worth 1. You don’t have to be afraid, I’ll not introduce you the Quantum mechanics of the music industry! Well, now that I think about it, maybe I will, but at least I’ll try to make it as easy to understand as possible!

While we applied calculations to weight on par all formats and to balance appropriately equivalent album sales of an artist into his original recordings, the final results were nothing else than real sales. The Beatles did sell 406 million equivalent albums, Michael Jackson did sell 324 million and so on. Basically, a CSPC approach of an artist consists in 3 steps:

  1. to define raw sales of all records
  2. to weight all raw sales as per the format concerned
  3. to re-assign sales of all secondary packages into the original recording
Why the success of an artist differs from the worth of his catalog

What does it mean when 2 artists end on the same CSPC total? Technically, it means their respective catalog sold the same number of equivalent album units. Functionally, it means the worth of their catalogs is the same. Obviously, careers of these artists may differ in many ways. One may have released more albums, at different times with different market sizes and their recordings may have been exploited differently. If two artists sold 50 million CSPC units each, but the first one issued 10 albums and the second one issued only 2, it is rather clear that the former has been the most successful.

Should we calculate an average per album then? It would be a very bad idea. If we did that in 2005, we would have found out that Norah Jones and Dido were as successful as the biggest artists of all-time. It is something to get a pair of successful albums, it is something else to build a catalog as valuable as the one of the Beatles. Plus, an average wouldn’t help in sorting the impact of the exploitation.

The Commensurate Sales to Popularity Concept defines the worth of an artist’s catalog as it stands. While it seems natural to believe that the success of an artist is defined by how much he sold, it’s only true if his full sales potential has been achieved. In real life, the exploitation of an entire catalog can’t have been perfectly optimized all along the artist’s career, there have been lost value along the road. In other words, all artists could have sold better.

What if I tell you that I found a way to identify which artists have lost the most value? A way to prove that even if an artist sold less than some other one, he is been the most successful still? I should warn you – not all of you will like the results! That’s the way it is though and as previously mentioned, our CSPC lists will stick to purely verified sales so there is no need to worry.

Now that I have set the overall idea, let’s introduce the Artist Success Rating which rates the absolute success of an artist independently of how his records were exploited by his record company. This rating uses in part CSPC results but pushes the reasoning into higher level of thoughts to make up from the lost value. Our goal today is to found a way to resolve this formula:


ASR:     Artist Success Rating
CSPC:   Commensurate Sales to Popularity Concept
LV:        Lost Value

MJD i dont know if im reading this wrong but im sort of confused: What is the difference between CSPC and ASR and how does it apply to any artists ranking among music history? Also, Billboard recent celebrated its 60th anniversary and has updated its list of top ten most successful artists and i was wondering if you could do a break down on it (i mean i could help as i have the data but i just want to see it in text lmao)


So when talking about the most successful artists, ASR is more accurate?


Their numbers are really strange and unbelievable, but there are those who believe that.


Where’s Nicki Minaj?!

Mario Axel

Hi, MJD.

About the records sold in page 5, Rihanna has 433,373,000.
Can you break down this number?



Hi MJD!!
Congratulations for this new introduction the ASR. I wanted to know because it is been over a week, if there are a new CSPC articles for example Sting & The Police and Aerosmith
I hope you will answer me, I am curious about your answer.


Thank you for answering dear MJD. I suppose this great artist is Phil Collins. Did I guess ?


My guess is Billy Joel. Then Phil Collins. I hope Garth Brooks is next in line too cos he really sold a lot in the 90s.


Took me a bit to understand this but now I fully get it and it is a great method! Thank you for this MJD 🙂

Stephon Jackson

I still don’t understand this fully. But I guess…


As always your concept is a lie and irrelevant for the music industry. That’s why you lost your credibility across social medias


One direction have not sold 143 million records! Surely that is a mistake?


Hi again, MJD

I need a help to understand some things.
In Adele’s table. Why for example Live at Royal Albert Hall that sold 3.580.000 brings 52.8M EAS?

How do you get this number? Do I miss something? I almost understand all the process you create…

Would love your thoughts, please comment.x
