How the Global 100 works

The Global 100 is ChartFM's collective music chart. Unlike streaming rankings, which count automatic and passive plays, the Global 100 is built from users' deliberate choices: each position on the collective ranking reflects how much a song was valued by the people who curated their personal lists that week.

The result is a chart that represents the community's real taste, not what an algorithm recommended or what played most often in shuffle mode, but what users consciously chose as the most important songs of their weeks.

ChartFM's scoring system uses a geometric curve: the song in 1st position on a chart is worth 1,000 points, and each position below is worth 95% of the previous position. So 2nd position is worth 950 points, 5th is worth 815, 10th is worth 630, 50th is worth 81, and 100th (the last possible position) is worth 6.

This curve was chosen on purpose: it values the top of personal charts more than volume. A song that appears on few charts, but always in the top positions, scores higher than a song that appears on many charts only in final positions.

These points are summed across every chart published that week. This rewards songs that users truly highlight, not just the most mentioned ones.

Every user who publishes a weekly chart contributes equally to the Global 100. There's no different weight based on follower count, time on the platform or history. A new user has the same impact as someone who's used ChartFM for two years.

This is intentional: the ranking should reflect the whole community, not just the profiles with the most followers. This creates the conditions for independent artists and personal discoveries to appear on the ranking when they're genuinely valued by several music fans at once.

Every week, the global ranking is recalculated from scratch. A song that led the ranking for three consecutive weeks can disappear entirely if no user includes it in the new week.

The system automatically identifies three types of movement: debut (the song appears on the ranking for the first time), return (it comes back to the ranking after being off it) and movement (rising or falling compared to the previous week).

With a few weeks of history you can see each song's behavior: releases enter high and drop fast; classics stay weeks in the middle of the table; songs from smaller artists rise gradually, as more people discover them.

There are three separate moments here, and it helps to keep them apart. The measured week runs Monday to Sunday and closes on Sunday at 23:59. Its ranking is published a few days later, Wednesday at 08:00 (Brasília time). The submission cutoff is always one hour before, Wednesday at 07:00 (Brasília time), so you can publish a chart for a week that has already ended and it still counts. At publication, the result is stored and becomes a permanent record, which is what preserves the history of every previous ranking.

A chart published after the cutoff does not enter that week's ranking. It stays published and visible on your profile, and its points count towards your chart's own aggregates, but the Global 100 for the week that just closed was already calculated without it.

The complete history of previous weeks is available on the Global 100 page. You can navigate between weeks and see how the ranking evolved over time.

On major streaming platforms, a song rises on the ranking when it's played, regardless of whether it was consciously chosen or played in shuffle mode. This favors algorithmically promoted songs and creates rankings that often don't reflect what people actually like.

On ChartFM, every position requires an intentional decision from the user. No one ends up on a chart by accident. This makes the Global 100 a closer portrait of what people truly like, especially for independent artists who have loyal fan bases but less investment in algorithmic promotion.
