Selector · a portfolio project
A fruit fly's brain picks your next song.
A personal taste engine built from your own streaming-history export. With recommendations and audio features gone from the public API since 2024, it works from what you own: your listening history, audio features measured from public previews, and the fly's olfactory circuit, wired from the real FlyWire connectome, as the similarity engine.
Watch the fly brain pick a track, live →Your export never leaves this browser tab.The zip is unpacked and analysed right here in JavaScript. There is no upload and no server that could receive it. Close the tab and it's gone.
How do I get my export?
On spotify.com go to Account → Privacy settings → Download your data, tick Extended streaming history, and confirm the email Spotify sends (unconfirmed requests are silently dropped). It can take up to 30 days to arrive. The sample listener above is synthetic: invented timestamps, skips and habits over real catalog tracks.
