Henrik has revealed to us the formula used to calculate the rankings of artists. One further question I have is how this changes (if at all) to determine the artist decade rankings.

For instance, if a similar formula is used, is it still the top 6 albums and songs? Are the rankings that are used all-time rankings, or decade rankings?

Any input would be greatly appreciated!

The same formula is used for the all-time artist list and the decade artist lists. So it would be possible for an artist with 6 half-acclaimed albums and songs from each decade to be fairly high in the decades lists and a bit further down in the all-time list.

I hope this answered your question, Moonbeam.

I think so, Henrik. So It Takes a Nation of Millions to Hold Us Back gets a rank of 18 in the formula and not a rank of 1 because it's the highest ranked 80s album, right?

Correct.
