Musical DNA Extractor takes a long listening history and distills it into a single chart — tempo, key, valence, acousticness, energy — that reads like a personality test for the way someone listens.

The idea
Most “year in review” features summarise what you listened to. This is an attempt to summarise how you listen: the shape of the music itself, not the metadata around it.
Current state
Work in progress. The pipeline runs end-to-end on a sample dataset; the visualisation is the part still being figured out.
