A genre label needs a source
A Spotify pie chart can look personal without explaining what it divided. Before interpreting it, ask whether the slices represent artists, tracks, plays, minutes or labels assigned by another service. Those are different datasets. A chart title should name the unit and period.
The supported streaming-history fields describe listening events; they do not supply a ready-made, reliable genre for every record. SnapSong therefore shows an artist share chart from your imported durations. It does not relabel those artists as genres or infer musical characteristics from a title.
Four minutes + two minutes = six minutes
4 ÷ 6 × 100; four minutes of the example.
2 ÷ 6 × 100; two minutes of the example.
All six supplied listening minutes.
Read a Spotify genre chart in five checks
- Find the data source: account connection, a history export or a manually tagged list.
- Find the date range and the final observation date.
- Find the weighting: each artist once, every record, or listening duration.
- Check how an artist with several genre labels is counted.
- Look for unknown labels and rounding. A missing category should not disappear without explanation.
Why two genre charts can disagree
Imagine Artist A has two labels and Artist B has one. Counting each label occurrence creates a different denominator from splitting each artist’s listening time between its labels. A tool that counts only your top artists also excludes the rest of your history. These are methodological choices, not necessarily mistakes, but the chart should explain them.
Make a small manually labelled example
Create a worksheet with artist, listening minutes, label source and assigned category. If you choose the labels yourself, call them your categories. For a one-category-per-artist demonstration, assign A’s four minutes to “Category 1” and B’s two minutes to “Category 2”. The shares are two-thirds and one-third. This is a learning exercise, not a claim that either artist belongs to a particular genre.
Keep an “Unknown” group for music you have not classified. If you permit several labels, state how the minutes are divided. Do not simply count the same minutes in several slices and label the result a share of total time.
Use the chart to choose a listening experiment
An interesting next step is to try a few tracks outside your usual artist mix, then revisit what you saved. A pie chart cannot determine personality, cultural identity or musical value. Use it to ask a question rather than to assign yourself a fixed label.
Try an explainable chart
Open the local history dashboard, choose the six-minute example and inspect the artist-time chart and table together. Import your own files only if you want to. The displayed artist percentages use all music time in the selected range, even when only the leading artists appear in the graphic.
