• 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)

  • ...

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.

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, add the following script to include these tags:

$setmulti(albumartists,%_albumartists%)
$setmulti(albumartistssort,%_albumartists_sort%)
