A simple Python-based Last.fm scrobbler for BluOS.
Fill in myconfig-example.py and rename it to myconfig.py.
For the LASTFM_* variables, detailed instructions are available in the Last.fm API documentation.
In summary, you first need to apply for an API key here. Providing only an application name in the form is sufficient. You will then receive an API key and secret that you need to copy in LASTFM_API and LASTFM_SECRET respectively.
The next step is to obtain an authorization token. You can follow the instructions here. In short, go to http://www.last.fm/api/auth?api_key={YOUR_API_KEY}&cb=http://localhost:5555 after you make sure nothing is running at port 5555. Click "Allow Access" and copy the token from the resulting URL (e.g. http://localhost:5555/?token={TOKEN_YOU_WANT}). Copy the token in LASTFM_TOKEN.
Finally, run:
$ python3 ./lastfm-session-key.py
This will print an XML response which will contain the session key within the <key> tags. Copy the session key in LASTFM_SESSION_KEY. Note that the session key never expires, so you only need to do this once.
Update the BLUOS_IP with the IP address of your BluOS device. BLUOS_PORT is the port number of the service.
You can read more at the BluOS API.
The variable SCROBBLE_AFTER defines the seconds of playtime after which a new song will be scrobbled.
The variable SCROBBLE_SERVICES defines the services that will be scrobbled. Only Tidal and the local library (LocalMusic) have been tested, but it should be extendable to others.
The script can be executed as follows:
$ python3 ./bluos-scrobbler.py
Note that in case of songs with multiple artists that have an artist tag of the form artist1, artist2, artist3, the script will scrobble it with only the first artist. Similarly, the script will remove any "(Remastered)" information from the track and album title.
In a Linux environment, such as a Raspberry Pi, you can install it to run as a service by executing:
$ ./install-as-service.sh
You can restart the service:
$ ./restart.sh
You can follow the output in the system journal as follows:
$ ./log.sh
The Last.fm library, lastfm.py is based on the lastfm-scrobbler.
