A browser extension created for people who listen to music online through their browser, and would like to keep an updated playback history using scrobbling services, such as Last.fm, Libre.fm and ListenBrainz. Available for Chrome, Chromium-based browsers (Opera, Vivaldi, etc), Firefox, and Safari (macOS and iOS).
It’s a term invented by Last.fm that didn’t really catch on more generally because it’s too silly even for the Internet.
By Audioscrobbler, which merged later with last.fm
I never never cared about my own or other people’s music listening history. And I never talked to someone who does. So I never needed a word for the thing, I guess.
