More than a most-played list
A ranking that can explain itself.
CAИON does not simply sort Albums by raw plays. It weighs endurance, returns and listening depth to recognise the music that genuinely stayed with you. Open any ranked Album, Artist or Track to see the evidence behind its placement.
Endurance
Did it stay important across years, rather than one intense period?
Returns
Did you keep coming back to it after time away?
Depth
Did your listening reach beyond one familiar Track?
Receipts
Plays, active periods, records and movement stay available underneath.
One history. Several clocks.
Your listening life, from the permanent archive to the present moment.
Multiplicity reads the same history at different speeds. Lifetime identity, the current month, individual years and the records underneath all stay connected.
ROTATIOИ
The current month.
Your monthly listening view, ranked by Average Equivalent Plays.

How It Works
How Multiplicity works.
01
Connect your history
Link Last.fm or upload an Apple Music export. Spotify and several other services can feed Multiplicity through Last.fm.
02
Build your CAИON
Multiplicity ranks Albums, Artists and Tracks from your listening history. Where available, the supporting evidence stays visible.
03
Check back over time
ROTATIOИ updates monthly. New records appear as you listen. Saved editions show how a CAИON changed.
No personality test. No self-reported taste labels. The listening record does the work.
Your history. Your archive.
Private by default. Share only what you choose.
Your source history, private ratings and listening evidence stay yours. Public Profiles and shared CAИON editions reveal only what you choose to publish.

Taste Families
Your listening has a shape.
CAИON reads broad patterns across your ranked Albums and places your archive within one of six Taste Families. It is a lens on real listening history, not a personality quiz.
The Dream Archive
Atmosphere, texture, memory, haze.
The Noise Frontier
Rupture, friction, extremity, experimentation.
The Rhythm System
Pulse, movement, groove, kinetic density.
The Formalists
Structure, precision, rigour, composition.
The Warm Current
Melody, intimacy, warmth, melancholy.
The Archive Modernists
Breadth, balance, restraint, cross-era range.
Explore the Taste Families
Six broad shapes. One becomes yours through the Albums you actually kept returning to.

FROM THE FOUNDER
I built Multiplicity because play counts were never enough.
For years, I kept my own obsessive music archive: Albums rated Track by Track, rankings adjusted over time, records tested against repeat listens and favourites that rose or fell as the evidence changed.
Multiplicity turns that instinct into a system anyone can use. Not simply ‘what did you play most?’, but what remained important when your listening is ranked, remembered and given shape over time.
Same listening history. A deeper read.

Questions
Before you build.
Is Multiplicity a personality quiz?
No. Rankings and identity are derived from real listening history. Taste Families are an interpretation of that record, not a questionnaire.
Is my listening history public?
No. Your source data and private evidence stay private. You decide whether to publish a Profile or share a saved CAИON edition.
What can I build for free?
Your permanent Top 50 CAИON is free. Deeper archive access is available through Centurion, Vault or an earned referral reward.
Which services work?
Last.fm connects directly. Apple Music works through a data export. Spotify and many other services can reach Multiplicity through Last.fm tracking.
Does my CAИON change?
Yes. You can regenerate it as your history grows. Saved editions remain preserved, so you can see how your musical identity moved over time.
