# LMS - Lightweight Music Server
|
|
|
|
[](https://github.com/epoupon/lms/releases)
|
|
|
|
_LMS_ is a self-hosted music streaming software: access your music collection from anywhere using a web interface!
|
|
|
|
A [demo instance](http://lms-demo.poupon.dev) is available. Note the administration panel is not available.
|
|
|
|
## Main features
|
|
* Recommendation engine
|
|
* Audio transcode for maximum interoperability and low bandwith requirements
|
|
* Multi-value tags: `genre`, `albumgenre`, `mood`, `albummood`, `albumgrouping`, ...
|
|
* Artist relationships: `composer`, `conductor`, `lyricist`, `mixer`, `performer`, `producer`, `remixer`
|
|
* [MusicBrainz Identifier](https://musicbrainz.org/doc/MusicBrainz_Identifier) support to handle duplicated artist and release names
|
|
* [ListenBrainz](https://listenbrainz.org) support for:
|
|
* Scrobbling and synchronizing listens
|
|
* Synchronizing 'love' feedbacks
|
|
* ReplayGain support
|
|
* User management, with several authentication backends, see [Deployment](INSTALL.md#deployment)
|
|
* Subsonic API
|
|
|
|
## Music discovery
|
|
_LMS_ provides several ways to help you find the music you like:
|
|
* Tag-based filters (ex: _Rock_, _Metal_ and _Aggressive_, _Electronic_ and _Relaxed_, ...)
|
|
* Recommendations for similar artists and albums
|
|
* Radio mode, with endless filling of the play queue with tracks similar to what is there
|
|
* Searches in album, artist and track names (including sort names)
|
|
* Starred Albums/Artists/Tracks
|
|
* Various tags to help you filter your music: _mood_, _albummood_, _albumgenre_, _albumgrouping_, ...
|
|
* Random/Starred/Most played/Recently played/Recently added for Artist/Albums/Tracks, allowing you to search for things like:
|
|
* Recently added _Electronic_ artists
|
|
* Random _Metal_ and _Aggressive_ albums
|
|
* Most played _Relaxed_ tracks
|
|
* Starred _Jazz_ albums
|
|
* ...
|
|
|
|
## Subsonic API
|
|
The API version implemented is 1.16.0 and has been tested on _Android_ using _Subsonic Player_, _Ultrasonic_, _Symfonium_, and _DSub_.
|
|
Since _LMS_ uses metadata tags to organize music, a compatibility mode is used to browse the collection when using the directory browsing commands.
|
|
The Subsonic API is enabled by default.
|
|
|
|
__Note__: since _LMS_ may store hashed and salted passwords or may forward authentication requests to external services, it cannot handle the __token authentication__ method. You may need to check your client to make sure to use the __password__ authentication method.
|
|
|
|
## About tags
|
|
_LMS_ relies exclusively on tags to organize your music collection.
|
|
|
|
### Filtering
|
|
You can specify the tags you want to use to filter your collection. By default, `genre`, `albumgrouping`, `mood` and `albummood` tags are used.
|
|
In the administration panel, you can set whatever tags you want, even custom tags.
|
|
|
|
__Note__: you can use the `lms-metadata` tool to have an idea of the tags parsed by _LMS_ using [TagLib](https://github.com/taglib/taglib).
|
|
|
|
### Multiple album artists
|
|
_LMS_ requires the `ALBUMARTISTS` and `ALBUMARTISTSSORT` tags to properly handle multiple album artists on the same album. As they are a custom tags, you may need to setup your favorite tagger to add them.
|
|
|
|
__Note__: if you use [Picard](https://picard.musicbrainz.org/), add the following script to include these tags:
|
|
```
|
|
$setmulti(albumartists,%_albumartists%)
|
|
$setmulti(albumartistssort,%_albumartists_sort%)
|
|
```
|
|
|
|
## Keyboard shortcuts
|
|
* Play/pause: <kbd>Space</bbd>
|
|
* Previous track: <kbd>Ctrl</kbd> + <kbd>Left</kbd>
|
|
* Next track: <kbd>Ctrl</kbd> + <kbd>Right</kbd>
|
|
|
|
## Security considerations
|
|
_Wt_ (the web framework used) has some [built-in security measures](https://www.webtoolkit.eu/wt/features#security), but _LMS_ also has some too:
|
|
* to mitigate brute force login attempts, _LMS_ uses an internal login throttler based on the client IP address. The `Client-IP` or `X-Forwarded-For` headers are used to determine the real IP adress, so make sure to properly configure your reverse proxy to filter or even erase the values (see example in [INSTALL.md](INSTALL.md)).
|
|
* all passwords are stored hashed and salted using [bcrypt](https://fr.wikipedia.org/wiki/Bcrypt)
|
|
* all the resources relative to the music collection (tracks, covers, etc.) are private to an anthenticated session
|
|
|
|
