Two orders side by side: one the app works out from your listening, one you settle yourself, two records at a time.
Nothing you rated four will ever sit above something you rated five, in either order.
Everything below is about how records you gave the same score are ordered against each other. With half stars, that is most of them.
Inside a star tier it looks at how often you came back to a record, over how long, how recently, how much of that artist is in your log, and whether you marked it a cornerstone.
Coming back to something counts for the most. It is the only signal you did not choose to send. A rating is an opinion. A re-listen is what you did.
The reason is printed under each row, along the lines of 'came back to it eleven times over four years', so you can see why a record sits where it does. If your log has nothing to say about a record yet, that line is left blank.
The app shows you two records you gave the same score and asks which is actually higher, with a clip of each so you are not choosing between two things you half remember. You can skip a pair, and you can start over.
Your answers are kept separate from the worked out order rather than mixed into it. They are two readings of the same log, and side by side you can see where you disagree with the app.
Once your log has some history behind it, the ranking reads like a chart: what went up, what held, the highest a record has ever been, and how long it has been on.
None of that is stored. It is worked out by replaying your ranking as it stood at earlier dates, because every log carries the date it was filed.
