lastcast 0.1.8

Scrobble music to last.fm from Chromecast.

Scrobble music playing on Chromecast devices to last.fm

Because I was annoyed that Spotify doesn’t scrobble to last.fm when using Chromecast. Currently will scrobble tracks playing on Spotify and Google Play Music.

pip install lastcast

To setup a configuration for lastcast, either modify example.lastcast.toml as necessary and write it to ~/.lastcast.toml, or use the config creation tool:

lastcast --wizard

Once the configuration file is in place, run lastcast to connect to the Chromecast and start scrobbling.

Detailed macOS setup

(for anyone not familiar with Python and pip)

Enter the following commands in your Terminal (Terminal.app, iTerm2, etc.):

1. sudo easy_install pip

2. sudo pip install --upgrade lastcast --ignore-installed six

3. lastcast --wizard

This will prompt you to create a last.fm API application and then ask for your login information, which will only be stored locally on your computer.

You may get an error on step 2 about cc missing. If this is the case, install xcode by running xcode-select --install and retry step 2.

Now everything should be set up. When you want to start scrobbling, simply run lastcast in the terminal.

Generally, I run lastcast like so: while true; do lastcast; sleep 5; done. This will help in case lastcast crashes for whatever reason (please open an issue if you see something go wrong!)

Linux / systemd instructions

1. sudo pip install --upgrade lastcast

2. lastcast --wizard

3. Edit the code block below as needed (remember to fill in the config path!) and write to /usr/lib/systemd/system/lastcast.service (or /etc/systemd/system/lastcast.service if the directory doesn’t exist)

4. sudo systemctl daemon-reload

5. sudo systemctl enable lastcast

No Chromecast devices found?

It is possible that an incompatible version of netifaces will prevent lastcast from finding any Chromecast devices on your network. This is known to affect Windows 10 with netifaces==0.10.5 installed.

The fix, as described in this StackOverflow answer is simply to uninstall the wrong version and manually install netifaces==0.10.4.

$ pip uninstall netifaces
$ pip install netifaces==0.10.4

If you still can’t discover any Chromecasts, please open an issue.
