bijou.fm is a visualization and analysis tool for your music listening data since 2016.
It works by connecting to your Last.fm account and/or Spotify account.
It's available as web and native iOS and Apple TV apps.
It was first launched as lists.fm in 2016 which then turned into sergei.fm somewhere around 2020 and then into bijou.fm in 2023. First only as a web app, then as an iOS app and now also as an Apple TV app.
It's still in beta. Please reach out if you find any bugs or have feature requests!
