-Why MusicMuster?
-----------------
-
-In January 2022 I started my show on `Mixcloud
-<https://www.mixcloud.com/KeithsMusicBox/>`. Until then, my show had
-been on an internet radio station which required me to use a Windows
-playout system. As I only use Linux, I had to set up a Windows PC
-specifically for that purpose. The system I had to use had what I felt
-were shortcomings in various areas.
-
-Once I moved to Mixcloud I searched for a Linux equivalent that didn't
-have the same shortcomings but was unable to find one that met my
-criteria. I decided to see how practical it would be to write my own,
-and MusicMuster was born.
-
-What is MusicMuster?
---------------------
-
-It is a Linux-based music player. Whilst it could be used as a general
-home music player, there are much better applications for that role.
-**MusicMuster** has been specifically designed to support the
-production of live internet radio shows.
-
-Features
---------
-
-* Database backed
-* Can be almost entirely keyboard driven
-* Open multiple playlists in tabs
-* Play tracks from any playlist
-* Add notes/comments to tracks on playlist
-* Automatatic colour-coding of notes/comments according to content
-* Preview tracks before playing to audience
-* Time of day clock
-* Elapsed track time counter
-* Time to run until track starts to fade
-* Time to run until track is silent
-* Graphic of volume from 5 seconds (configurable) before fade until
-  track is silent
-* Optionally hide played tracks in playlist
-* Button to drop playout volume by 3dB for talkover
-* Playlist displays:
-    * Title
-    * Artist
-    * Length of track (mm:ss)
-    * Estimated start time of track
-    * Estimated end time of track
-    * When track was last played
-    * Bits per second (bitrate) of track
-    * Length of leading silence in recording before track starts
-    * Total track length of arbitrary sections of tracks
-    * Commands that are sent to OBS Studio (eg, for automated scene
-      changes)
-* Playlist templates
-* Move selected or unplayed tracks between playlists
-* Download CSV of tracks played between arbitrary dates/times
-* Search for tracks by title or artist
-* Automatic search of current and next track in Wikipedia
-* Optional search of any track in Wikipedia
-* Optional search of any track in Songfacts
-
-
-Requirements
-------------
-
-.. note:: MusicMuster has only been tested on Debian 12, "Bookworm";
-   however, it should run on most contemporary Linux systems.
-
-The :doc:`installation` page explains how to build MusicMuster in its
-own environment which will automatcally install all requirements
-except the database. The current version of MusicMuster uses MariaDB
-version 10.11; however, any recent version of MariaDB should suffice.
-
-MusicMuster is a Python 3 application and requires Python 3.8 or
-later.

-<h2>Why MusicMuster?<a class="headerlink" href="#why-musicmuster" title="Permalink to this heading">#</a></h2>
-<p>In January 2022 I started my show on <cite>Mixcloud
-&lt;https://www.mixcloud.com/KeithsMusicBox/&gt;</cite>. Until then, my show had
-been on an internet radio station which required me to use a Windows
-playout system. As I only use Linux, I had to set up a Windows PC
-specifically for that purpose. The system I had to use had what I felt
-were shortcomings in various areas.</p>
-<p>Once I moved to Mixcloud I searched for a Linux equivalent that didn’t
-have the same shortcomings but was unable to find one that met my
-criteria. I decided to see how practical it would be to write my own,
-and MusicMuster was born.</p>
-</section>
-<section id="what-is-musicmuster">
-<h2>What is MusicMuster?<a class="headerlink" href="#what-is-musicmuster" title="Permalink to this heading">#</a></h2>
-<p>It is a Linux-based music player. Whilst it could be used as a general
-home music player, there are much better applications for that role.
-<strong>MusicMuster</strong> has been specifically designed to support the
-production of live internet radio shows.</p>

-<div class="admonition note">
-<p class="admonition-title">Note</p>
-<p>MusicMuster has only been tested on Debian 12, “Bookworm”;
-however, it should run on most contemporary Linux systems.</p>
-</div>
-<p>The <a class="reference internal" href="installation.html"><span class="doc">Installation</span></a> page explains how to build MusicMuster in its
-own environment which will automatcally install all requirements
-except the database. The current version of MusicMuster uses MariaDB
-version 10.11; however, any recent version of MariaDB should suffice.</p>
-<p>MusicMuster is a Python 3 application and requires Python 3.8 or
-later.</p>

-Introduction
-============
-
-Why MusicMuster?
-----------------
-
-In January 2022 I started my show on `Mixcloud
-<https://www.mixcloud.com/KeithsMusicBox/>`. Until then, my show had
-been on an internet radio station which required me to use a Windows
-playout system. As I only use Linux, I had to set up a Windows PC
-specifically for that purpose. The system I had to use had what I felt
-were shortcomings in various areas.
-
-Once I moved to Mixcloud I searched for a Linux equivalent that didn't
-have the same shortcomings but was unable to find one that met my
-criteria. I decided to see how practical it would be to write my own,
-and MusicMuster was born.
-
-What is MusicMuster?
---------------------
-
-It is a Linux-based music player. Whilst it could be used as a general
-home music player, there are much better applications for that role.
-**MusicMuster** has been specifically designed to support the
-production of live internet radio shows.
-
-Features
---------
-
-* Database backed
-* Can be almost entirely keyboard driven
-* Open multiple playlists in tabs
-* Play tracks from any playlist
-* Add notes/comments to tracks on playlist
-* Automatatic colour-coding of notes/comments according to content
-* Preview tracks before playing to audience
-* Time of day clock
-* Elapsed track time counter
-* Time to run until track starts to fade
-* Time to run until track is silent
-* Graphic of volume from 5 seconds (configurable) before fade until
-  track is silent
-* Optionally hide played tracks in playlist
-* Button to drop playout volume by 3dB for talkover
-* Playlist displays:
-    * Title
-    * Artist
-    * Length of track (mm:ss)
-    * Estimated start time of track
-    * Estimated end time of track
-    * When track was last played
-    * Bits per second (bitrate) of track
-    * Length of leading silence in recording before track starts
-    * Total track length of arbitrary sections of tracks
-    * Commands that are sent to OBS Studio (eg, for automated scene
-      changes)
-* Playlist templates
-* Move selected or unplayed tracks between playlists
-* Download CSV of tracks played between arbitrary dates/times
-* Search for tracks by title or artist
-* Automatic search of current and next track in Wikipedia
-* Optional search of any track in Wikipedia
-* Optional search of any track in Songfacts
-
-
-Requirements
-------------
-
-.. note:: MusicMuster has only been tested on Debian 12, "Bookworm";
-   however, it should run on most contemporary Linux systems.
-
-The :doc:`installation` page explains how to build MusicMuster in its
-own environment which will automatcally install all requirements
-except the database. The current version of MusicMuster uses MariaDB
-version 10.11; however, any recent version of MariaDB should suffice.
-
-MusicMuster is a Python 3 application and requires Python 3.8 or
-later.
