Spotify's "Account privacy" dashboard lets you bulk-export an "extended streaming history" (i.e. everything you've ever listened to).

I built this static tool for analyzing the resulting piles of data:

- Who are my top artists in December, across all years?

- Objectively speaking, what is actually my favorite Big Thief song?

- Why won't the cowards at Spotify admit what I know in my heart is the truth (that I am this year's top listener of the Masonna/Prurient split 'Annihiliationism')?

Your data never leaves your browser. Full source is on GitHub.[^1]

Spotify might take a day or two to generate your export; in the mean time, you can try the tool with my depersonalized demo data (link under the upload widget).

Enjoy!
