Prerequisites
Because Music Manager is a website based application, we first need to install some software in order to use it. We need a webserver and a database, the details are explained below.
Windows
WAMP stands for Windows Apache MySQL PHP, which means it is a bundle of software to display websites. The package is available at www.wampserver.com or at a direct download link.
After the download is finished, double click the downloaded file and just follow the instructions to install WAMP. After the installation is done, you will see a small icon in the taskbar from which you can control the WAMP server.

After installing, you will probably get a warning like the one below, click 'unblock' to allow your new apache server to work properly.

Before installing Music Manager it is necessary to modify the configuration of the web server. Left click on the icon in the taskbar and go to the menu Apache / Apache Modules. There you have to enable the option rewrite_module as shown below.

Next we have to restart the apache server by left clicking the icon and select Restart All Services.
Linux
In linux you can install the packages with the package manager supplied with your distribution:
Fedora
yum install php httpd mysqld mysqld-server php-mysql
Ubuntu
apt-get install php5 apache2 mysql-server php5-mysql
Edit the apache configuration file, which is usually located in /etc/httpd/conf/httpd.conf, so that the module mod_rewrite is enabled:
LoadModule rewrite_module modules/mod_rewrite.so
Now you are ready to install Music Manager.
