How to read a music chart
Updated 2026-10-19
A chart looks simple: a numbered list, number one at the top. But what that number means changes completely depending on who is counting and what they are counting. This guide explains the vocabulary and the traps, using the four Israeli charts Charty follows as examples.
A rank is a measurement, not a verdict
Every chart answers a narrow question. A radio chart answers "what is this station choosing to play, and how hard?" A store chart answers "what are people paying for or downloading right now?" A Shazam chart answers "what are people hearing out in the world and wanting to name?" None of them answers "what is the best song in the country", and none of them is wrong for failing to. When you read a chart, the first thing to check is the question it is asking.
The words you will see
- New entry — a song that was not on the previous version of the chart. On a weekly chart this usually means a fresh release or a song that just caught on.
- Climber / faller — a song that moved up or down since the previous version. Charty's weekly digest reports the biggest of each, measured against the last archived snapshot of the same chart.
- Peak — the highest position a song reached. A song can be a hit for months and still have a modest peak, or peak at number one for a single week.
- Re-entry — a song that dropped off and came back, often because of a TV moment, an anniversary or a viral clip.
- Chart period — the stretch of time a chart covers. Galgalatz publishes a date range such as "27-03/09/2026"; the iTunes and Shazam charts change continuously and have no fixed week.
Why the same song ranks differently everywhere
Look at one song on several charts and the numbers rarely match. A song might be number one on Shazam because people keep hearing it in a series and reaching for their phones, yet sit lower on radio because the station has only just added it. A veteran artist can dominate radio without ever troubling a sales chart. These gaps are the interesting part: a song that ranks high on charts measuring different things at once is a much stronger signal than a song that is high on only one. That is why the weekly digest lists songs charting in more than one place.
Small moves, big moves
Movement near the top of a chart is meaningful because the gaps between positions are large: moving from 3 to 2 can mean a real change in listening. Lower down, positions are packed tightly, so a jump of 40 places on a 200-song chart can be a handful of extra identifications. Treat movement lower in a long chart as noise unless it persists across several updates.
Daily versus weekly
A daily or continuously updated chart reacts to a single viral moment within hours. A weekly chart smooths that out and rewards songs that hold attention for days. Neither is better; they describe different speeds. Charty refreshes its data once a day, but only archives a new chart to History when the source publishes a genuinely new one.

Each of the four charts has its own quirks: read about the Galgalatz radio chart, the Shazam chart and the iTunes chart, or browse a short guide to the styles of Israeli music to put the names in context.
