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
• 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
  • ...

Note: depending on your database size and/or your hardware, the tag-based recommendation engine may significantly slow down the user interface. You can disable it in the administration settings.

About tags

LMS primarily relies on tags to organize your music collection but also supports browsing by directory using the Subsonic/OpenSubsonic API.

Filtering

It is possible to apply global filters on your collection using genre, mood, grouping, language, and by music library. More tags, including custom ones, can be added in the database administration settings.

Note: You can use the lms-metadata tool to get an idea of the tags parsed by LMS.

Multiple artists

LMS works best when using the default Picard settings, where the artist tag contains a single display-friendly value, and the artists tag holds the actual artist names. This ensures a cleaner, more organized representation of artist names, when multiple artists are involved.

Multiple album artists

While LMS can manage multiple album artists using the albumartist tag, it works better when using the custom albumartists and albumartistssort tags, similar to how it handles regular artist tags.

Note: if you use Picard, add the following script to include these tags:

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

Playlist support

LMS supports playlist files in m3u and m3u8 formats. These playlists are synced during the scan process and are available as public shared playlists.

Lyrics support

LMS supports lyrics in lrc files and embedded track metadata. Both synchronized and unsynchronized lyrics are supported.

Keyboard shortcuts

• Play/pause: <kbd>Space</kbd>
• Previous track: <kbd>Ctrl</kbd> + <kbd>Left</kbd>
• Next track: <kbd>Ctrl</kbd> + <kbd>Right</kbd>
