03 · Foundations
What Last.fm is actually measuring
A practical look at what scrobbles do and do not capture, and why your Chartwave results are only as complete as the listening history underneath them.
04 · Time windows
Why 1 week, 1 month, 3 month, 6 month, and 12 month views can feel so different

05 · Hot 10
How the Hot 10 differs from a raw Last.fm list
Why the Hot 10 feels more like a finished chart than a stats table, and what changes once hierarchy, movement, and design are doing part of the storytelling.

A practical explanation of how the big rank, movement arrow, and weekly streak each come from different layers of Last.fm data.
07 · Formats

How to read the Genre Drift graph without overthinking it, and what the lines actually tell you about short-term phases versus long-term listening anchors.

Why image coverage is uneven
Why some charts look nearly complete while others fall back to initials, and why that usually comes down to upstream metadata rather than a broken layout.

Why saving and sharing are not just extra features on Chartwave, but part of what makes the site feel more like a publishing tool than a private dashboard.
11 · Reading charts

Why one huge song can coexist with a different top artist, and what that mismatch usually reveals about the way people actually listen.
12 · Genres
Why genre tags sometimes look messy on Last.fm
Why Last.fm tags overlap, repeat, and sometimes look a little strange, plus how to read them without expecting a perfect genre taxonomy.
13 · Reading charts
Why some listening periods make better charts than others
