ChartFM Glossary

Chart (or "parada") is a user's personal weekly list, with up to 100 songs chosen and ordered by them. Each chart is published once a week and stays linked to the profile of whoever created it. The Global 100 is calculated from the sum of all published charts.

"Chart" is used elsewhere on ChartFM as a synonym for "parada", for example, the creation button at /create is called 'Create Chart'. Both terms describe the same thing: your personal weekly list of songs. There's no difference in meaning on the platform; use whichever you prefer.

Debut is when a song appears on the Global 100 for the first time. This happens when enough users include that song in their weekly charts for it to enter the collective ranking. A debut doesn't have to be a recent release, it can be an old song that has only now gained traction in the community.

Return is when a song reappears on the Global 100 after having been off the ranking for at least one week. Unlike a debut, a return indicates the song had appeared before, dropped off, and is being valued by users again. The system identifies this status automatically by comparing the current week with the song's history.

Peak is the best position a song has ever reached on the Global 100, considering its entire history. A song that reached 3rd position in one week and then dropped to 40th keeps its peak recorded as 3, even if it never returns to that level again.

Weeks on the ranking is the total number of times a song has appeared at any position on the Global 100, adding up every week since it started being calculated, not necessarily consecutively. A song can have many weeks on the ranking without ever having come close to the top; they're two independent metrics.

Snapshot is the frozen record of the Global 100 for a specific week, generated when that week closes. Once created, a snapshot never changes again, even if charts are edited afterward, that week's history stays exactly as it was calculated at closing time.

This is what guarantees ChartFM's history of previous rankings is always available for consulting, week by week, with no risk of being rewritten.

Global 100 is ChartFM's collective chart, calculated from the sum of points from every chart published by users during the week. Each position in each personal chart is worth a number of points, and the sum per song determines the final ranking.

The week's ranking is stored when the Global 100 is published, Wednesday at 08:00 (Brasília time), and does not change after that. To understand the formula behind the points, see the guide how scoring works; to understand the ranking as a whole, see how the Global 100 works.

Cup is ChartFM's knockout tournament between artists, played out bracket-style, similar to a football cup. It's a competition parallel to the Global 100, driven by community votes in each match, instead of chart points.

The full details on format, groups, stages and tiebreak criteria are on the /copa and /copa/regras. This glossary doesn't repeat those rules, it's just a pointer to where to find them.
