exploration

A track lasts three minutes, a session lasts an hour, and a new song has zero plays the day it drops. The interview is about blending collaborative filtering with audio content embeddings, surviving cold start on both sides, and reading a skip as the loud negative it is.

The whole product lives or dies on a feedback loop measured in seconds: a swipe is a label, and the next video has to reflect it. The hard part is exploring enough to discover what someone likes without trapping them in a filter bubble or amplifying junk.
