This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

WP SoundSystem


WP SoundSystem is a complete solution to manage music in WordPress.

Import, create and manage tracklists, play tracks, connect to popular music services, and more !

See it working on Spiff Radio

Unlike most plugins, WP SoundSystem is not embedding third-party widgets in WordPress.
It goes further by using its own customizable player : no brands, no logos, but your own data & design !

Playing tracks does not rely on a single service, since multiple links can be associated to a track (Youtube, Soundcloud, Spotify, audio files, anything!).


We have two types of tracklists : Playlists, and Radios.

But what the hell are Radios ?

Unlike Playlists, you cannot add, remove or reorder the tracks of a Radio : it is synced with an external URL, and updates seamlessly after a user-defined delay. This is something very specific to this plugin.

Check some Radios on Spiff Radio

For example, a Radio might be

  • Synced to a station website “now playing” page, cached for only 15 minutes since it is updated constantly on the remote side.
  • Synced to a Spotify playlist, cached for 1 day (or more) since there is only a few chances that its author might have updated it.

A Radio synced with a Spotify playlist of yours would bring an always up-to-date playlist to your visitors, without having to update your website.

You can also create a Radio to fetch a tracklist you like, then convert it to a (static) Playlist so you have a backup of it.

Any tracklists can be exported to the standard XSPF file format.


Tracks can be favorited and shared by your users frontend, or added to a new playlist on-the-fly.
Backend, you can query details from music services like MusicBrainz (The Open Music Encyclopedia) or Spotify.

Tracks Links

You can attach a bunch of links to any track; including links that can stream audio (Youtube, Soundcloud, audio files…) directly to our player!

Autolink (requires an API key)

If you don’t attach links to your track manually, you can enable our autolink module.
It will search for remote links and attach them to your tracks automatically.

Tracklist Importer

Import XSPF playlists using the Tracklist Importer.

If you have an API key, you could also import playlists from various services:, Spotify, SoundCloud, Deezer, Musicbrainz, Radionomy, Hypem, 8tracks, BBC, indieshuffle, Online Radio Box,, RadioKing, Reddit, SomaFM, Soundsgood,…

Custom setups are also available, if you are somewhat familiar with CSS selectors.

Frontend Importer on Spiff Radio


Our player uses of the MediaElement.js library, which is native in WordPress. It supports audio (& video) files, but also links from various services like Youtube or Soundcloud.
It has been extended with various features built on top of it, like a tracks queue or a scrobbler.
You can customize the design of this player the way you like, and extend its functions.

In addition of being able to scrobble on, every track favorited by a user connected to his account will also be loved on that service.

Users profiles will get a new music section that lists the user favorite tracks, tracklists, and the ones he created.
It will also fire new BuddyPress activity items.


WP SoundSystem is dev friendly, and has been designed to be extendable.

SoundSystem API

The SoundSystem API has been developed in Ruby in parallel of this plugin.
Get extra features by registering an API key !

Some of its feature are:

  • Playlist import from a lot of music services
  • the Autolink module, which will get audio sources for your tracks automatically.

Those are optionals, but are nice features to a solid plugin.
Consider getting one as a nice way to support the work done –hundred of hours– , and to ensure its durability.

Since the API is independent of the plugin, it might also be used by other developers.
