Scrobble YouTube Music to Last.fm and Libre.fm

Connect in a minute

1. In Cellar, open Settings ▸ Integrations.
2. Click Connect Last.fm (or Connect Libre.fm) and approve Cellar on the page that opens in your browser.
3. The row now reads "Connected as" and your username. Play a song and it shows as now playing on your profile.

When a song counts

• Your profile shows the track as now playing within a few seconds of starting it.
• A track scrobbles once you have heard half of it or four minutes of it, whichever comes first. A 3:00 song scrobbles at 1:30, a 12 minute DJ set at 4:00.
• Skip before that point and the play does not scrobble.
• Tracks shorter than 30 seconds and livestreams never scrobble.
• Each scrobble keeps the time you started the song.

These are the rules Last.fm sets for every scrobbler, so your charts stay comparable with plays from other apps.

Last.fm and Libre.fm together

Link one service or both. With both linked, every play goes to each of them, and disconnecting one leaves the other running. The connection follows your YouTube Music profile, so other computers you use Cellar on show it as connected the next time you open Settings.

Click Disconnect in the same row and scrobbling stops. If you revoke Cellar in your Last.fm settings instead, the row falls back to "Not connected" after your next play.
