Dscos isn't just another favourites list. It's a meta-ranking: a mathematical system that combines historic best-of lists for Brazilian music, weighing the judgement of specialists, critics and the listening public. The aim is to surface the 100 albums that truly define the Brazilian canon.
Reciprocal Rank Fusion
Instead of simply tallying points, we use a technique called Reciprocal Rank Fusion (RRF). With a straight point total, the gap between 1st and 2nd place looks the same as the gap between 99th and 100th. In music, that isn't how prestige works: the top of a list carries far more weight.
RRF rewards albums that consistently land near the top of multiple lists.
The factor k = 60 is the smoothing parameter. It ensures an album championed by many lists (consensus) can compete with one that topped a single list. Without it, lone outlier votes would dominate the ranking.
Source Weights
Not every list carries the same authority. We assign different weights to reflect each source's credibility, so expert opinion exerts a stronger pull on the final mix.

The Charles Gavin Bonus
Charles Gavin's 300 Important Albums of Brazilian Music is a special case: it has no ranked order. It's a curation of excellence, not a numbered countdown.
To fold it into the algorithm without breaking the positional logic, we treat inclusion in Gavin's selection as a seal of quality. Any album he chose receives a score equivalent to position 100 in a ranked list. In effect, the album earns an extra vote of confidence from one of Brazil's foremost musical scholars.
Equivalent to position #100
Minimum Requirement
To make sure the ranking reflects real consensus rather than one-off appearances, an album must feature in at least two different sources to qualify for the Top 100. This filters out records that show up on a single list and rewards those recognised across multiple perspectives.
The Result
Dscos is the product of three forces held in balance: Authority (source weights), Consensus (presence across multiple lists) and Distinction (high placements). The album at the top is the one that has withstood the scrutiny of different generations and different criteria for what makes a great record.
