I'd stopped scrobbling like 10 years ago, but recently got into it again.
My 16yo son discovered Last.fm and scrobblibg and got me to install the Jellyfin scrobbler plugin. And I recovered my old account! I got some boomer music jokes from him, but it was worth it.
Breaking free from their recommendation algorithm and dedicating time to discovering music has been a transformative experience.
I am delighted that numerous tools still utilize scrobbling. My favorite recent discovery is Tapmusic. [0]
