Maloja

Simple self-hosted music scrobble database to create personal listening statistics. No recommendations, no social network, no nonsense.

You can check my own Maloja page to see what it looks like (it's down fairly often because I use it as staging environment, that doesn't reflect the stability of the Maloja software!).

IMPORTANT: With the update 2.7, the backend has been reworked to use a password. With a normal installation, you are asked to provide a password on setup. If you use docker or skip the setup for other reasons, you need to provide the environment variable MALOJA_FORCE_PASSWORD on first startup.

IMPORTANT: With the update 2.9, the API endpoints have changed. All old endpoints should be redirected properly, but I recommend updating your clients to use the new ones.

Features

• Self-hosted: You will always be able to access your data in an easily-parseable format. Your library is not synced with any public or official music database, so you can follow your own tagging schema.
• Associated Artists: Compare different artists' popularity in your listening habits including subunits, collaboration projects or solo performances by their members. Change these associations at any time without losing any information.
• Multi-Artist Tracks: Some artists often collaborate with others or are listed under "featuring" in the track title. Instead of tracking each combination of artists, each individual artist competes in your charts.
• Custom Images: Don't rely on the community to select the best pictures for your favorite artists. Upload your own so that your start page looks like you want it to look.
• Proxy Scrobble: No need to fully commit or set up every client twice - you can configure your Maloja server to forward your scrobbles to other services.
• Standard-compliant API: Use existing, mature apps or extensions to scrobble to your Maloja server.
• Manual Scrobbling: Listening to vinyl or elevator background music? Simply submit a scrobble with the web interface.
• Keep it Simple: Unlike Last.fm and similar alternatives, Maloja doesn't have social networking, radios, recommendations or any other gimmicks. It's a tool to keep track of your listening habits over time - and nothing more.

How to install

Requirements

Maloja should run on any x86 or ARM machine that runs Python.

I can support you with issues best if you use Alpine Linux.

Your CPU should have a single core passmark score of at the very least 1500. When virtualizing or containerizing, Maloja does not benefit from multiple assigned cores.

500 MB RAM should give you a decent experience, but performance will benefit greatly from up to 2 GB.

PyPI

You can download the included script install_alpine.sh and run it with

	sh install_alpine.sh

You can also simply call the install command

	pip install malojaserver

directly (e.g. if you're not on Alpine) - make sure you have all the system packages installed.

From Source

Clone this repository and enter the directory with

	git clone https://github.com/krateng/maloja
	cd maloja

Then install all the requirements and build the package:

	sh ./install/install_dependencies.sh
	pip install -r requirements.txt
	pip install .

Docker

Pull the latest image or check out the repository and use the included Dockerfile.

Of note are these settings which should be passed as environmental variables to the container:

• MALOJA_DATA_DIRECTORY -- Set the directory in the container where configuration folders/files should be located
  • Mount a volume to the specified directory to access these files outside the container (and to make them persistent)
• MALOJA_FORCE_PASSWORD -- Set an admin password for maloja

You must publish a port on your host machine to bind to the container's web port (default 42010). Note that the Docker version uses IPv4 per default.

An example of a minimum run configuration to access maloja via localhost:42010:

	docker run -p 42010:42010 -v $PWD/malojadata:/mljdata -e MALOJA_DATA_DIRECTORY=/mljdata maloja

Extras

• If you'd like to display images, you will need API keys for Last.fm and Spotify. These are free of charge!

• Put your server behind a reverse proxy for SSL encryption. Make sure that you're proxying to the IPv6 or IPv4 address according to your settings.

• You can set up a cronjob to start your server on system boot, and potentially restart it on a regular basis:

@reboot sleep 15 && maloja start
42 0 7 * * maloja restart

How to use

Basic control

Start and stop the server in the background with

	maloja start
	maloja stop
	maloja restart

If you need to run the server in the foreground, use

	maloja run

Data

• If you would like to import all your previous last.fm scrobbles, use benfoxall's website (GitHub page). Use the command maloja import *filename* to import the downloaded file into Maloja.

• To backup your data, run maloja backup or, to only backup essential data (no artwork etc), maloja backup -l minimal.

• To fix your database (e.g. after you've added new rules), use maloja fix.

Customization

• Have a look at the available settings and specifiy your choices in /etc/maloja/settings.ini. You can also set each of these settings as an environment variable with the prefix MALOJA_ (e.g. MALOJA_SKIP_SETUP).

• If you have activated admin mode in your web interface, you can upload custom images for artists or tracks by simply dragging them onto the existing image on the artist or track page. You can also manage custom images directly in the file system - consult images.info in the /var/lib/maloja/images folder.

• To specify custom rules, consult the rules.info file in /etc/maloja/rules. You can also apply some predefined rules on the /admin_setup page of your server.

How to scrobble

You can set up any amount of API keys in the file authenticated_machines.tsv in the /etc/maloja/clients folder. It is recommended to define a different API key for every scrobbler you use.

Native support

These solutions allow you to directly setup scrobbling to your Maloja server:

• Tauon Desktop Player
• Web Scrobbler Browser Extension
• Multi Scrobbler Desktop Application
• Cmus-maloja-scrobbler Script
• OngakuKiroku Desktop Application (Mac)
• Albula Music Server
• Maloja Scrobbler Chromium Extension (also included in the repository) for Plex Web, Spotify, Bandcamp, Soundcloud or Youtube Music

Native API

If you want to implement your own method of scrobbling, it's very simple: You only need one POST request to /apis/mlj_1/newscrobble with the keys artist, title and key (and optionally album,duration (in seconds) and time(for cached scrobbles)) - either as form-data or json.

If you're the maintainer of a music player or server and would like to implement native Maloja scrobbling, feel free to reach out - I'll try my best to help. For Python applications, you can simply use the malojalib package for a consistent interface even with future updates.

Standard-compliant API

You can use any third-party scrobbler that supports the audioscrobbler (GNUFM) or the ListenBrainz protocol. This is still somewhat experimental, but give it a try with these settings:

GNU FM
Gnukebox URL	Your Maloja URL followed by /apis/audioscrobbler
Username	Doesn't matter
Password	Any of your API keys

ListenBrainz
API URL	Your Maloja URL followed by /apis/listenbrainz
Username	Doesn't matter
Auth Token	Any of your API keys

Audioscrobbler v1.2
Server URL	Your Maloja URL followed by /apis/audioscrobbler_legacy
Username	Doesn't matter
Password	Any of your API keys

Known working scrobblers:

• Pano Scrobbler for Android
• Simple Scrobbler for Android
• Airsonic Advanced (requires you to supply the full endpoint (yoururl.tld/apis/listenbrainz/1/submit-listens))
• Funkwhale (use the legacy API yoururl.tld/apis/audioscrobbler_legacy)
• mpdscribble (use the legacy API yoururl.tld/apis/audioscrobbler_legacy)

I'm thankful for any feedback whether other scrobblers work!

Manual

If you can't automatically scrobble your music, you can always do it manually on the /admin_manual page of your Maloja server.
