Sonos Last.fm Scrobbler

Automatically scrobble what's playing on your Sonos speakers to your Last.fm profile.

The problem

If you use Last.fm, you know the value of a complete listening history. Some of us have been scrobbling for 10, 15, even 20 years — and that data tells a story.

But Sonos doesn't support Last.fm. There's no native integration, no plugin, no setting to flip. Every song you play on your Sonos speakers is a gap in your scrobbling history.

The solution

sonos-lastfm is a lightweight CLI tool that monitors your local network for Sonos playback and scrobbles every track to Last.fm automatically.

Run it on any always-on device in your home — a Raspberry Pi, a Mac Mini, an old laptop, or any Linux server — and never miss a scrobble again. It works as a background daemon, so once you set it up, you can forget about it.

Get started in 2 minutes

1. Install

pip install sonos-lastfm

Requires Python 3.10+ and Sonos speakers on the same network.

2. Get a free Last.fm API key

You need an API key so the app can talk to Last.fm on your behalf. It's free and takes 30 seconds:

1. Open https://www.last.fm/api/account/create
2. Fill in the form — app name can be anything (e.g. "my sonos scrobbler"), other fields don't matter
3. Submit — you'll see your API key and Shared secret. Keep this page open, you'll need both in the next step

3. Run setup

sonos-lastfm setup

The setup wizard will ask for four things:

The wizard validates your credentials immediately, so you'll know right away if something's wrong.

4. Start scrobbling

sonos-lastfm run

That's it! Play something on your Sonos and it will show up on your Last.fm profile.

CLI usage

sonos-lastfm run                # start scrobbling (interactive, with progress bar)
sonos-lastfm run --daemon       # start scrobbling (no progress display, for services)
sonos-lastfm run --interval 5   # check every 5s instead of 1s
sonos-lastfm info               # show account info and recent scrobbles
sonos-lastfm recent             # show last 10 scrobbled tracks
sonos-lastfm show               # show stored credentials (masked)
sonos-lastfm reset              # delete stored credentials

All run options: sonos-lastfm run --help

Run as a systemd service

Create ~/.config/systemd/user/sonos-lastfm.service:

[Unit]
Description=Sonos Last.fm Scrobbler
After=network-online.target

[Service]
Type=simple
ExecStart=%h/.local/bin/sonos-lastfm run --daemon
Restart=on-failure
RestartSec=10

[Install]
WantedBy=default.target

Then:

systemctl --user daemon-reload
systemctl --user enable --now sonos-lastfm
journalctl --user -u sonos-lastfm -f   # watch logs

In daemon mode, only song changes, scrobbles, and errors are logged.

AI-powered setup

Want an AI agent to handle the full setup for you — installing, configuring credentials, and setting up a persistent daemon? Use the included setup skill with any agent that supports open agent skills (Claude Code, Cursor, Windsurf, Codex, etc.).

Option A — Install the skill directly (no clone needed):

npx skills add denya/sonos-lastfm@setup-sonos-lastfm

Then ask your agent to "set up sonos-lastfm as a daemon."

Option B — Clone the repo and use the skill from source:

git clone https://github.com/denya/sonos-lastfm.git
cd sonos-lastfm
npx skills add ./skills/setup-sonos-lastfm

The skill covers Linux (systemd), macOS (launchd), and Windows (Task Scheduler), guides you through getting Last.fm API keys, and ensures you're always running the latest version from PyPI.

Scrobble rules

• Track is scrobbled after 25% played (configurable via --threshold) or 4 minutes, whichever comes first
• Same track won't be scrobbled again within 30 minutes
