Here you can enter a template for the string to be displayed on the tray icon tooltip.

This template is used as skeleton for the tray icon tooltip and includes several tags.
The tag is a placeholder for different parts of string. The following tags are currently
available:

%D - Disc title

%A - Artist name

%T - Current track time

%t - Track name

%n - Track number

For example, the default CoolCD template is:
CoolCD: %A - %t [%n] (%T)

When CoolCD Studio displays the tray icon tooltip it will construct resulting string
using this template and the resulting string will be something like that:
CoolCD: Gregorian - Losing My Religion [8] (1:38)
