Additional music can be added by placing sound files into Dataa/Music folder following this naming convention

musicmode_runningNumber.fileformat, so for example:

Mainmenu_001.mp3
Mainmenu_002.ogg
Laptop_002.ogg
Tactical_003.wav

*****************************************************************
Different musicmodes are

Mainmenu_ 		<-- Mainmenu music
Laptop_ 		<-- Laptop music
Tactical_		<-- Tactical with nothing special going on
Enemy_			<-- Tactical, enemy present
Battle_			<-- Tactical, enemy present and visible
Victory_		<-- Tactical, battle victory
Death_			<-- Tactical, battle defeat
Creepy_			<-- Tactical, creatures present

Music files can be .mp3, .ogg or .wav formats and 100 songs in each category is supported.
The running numbering starts from 000

*****************************************************************
A few filenames are treated in a special way to facilitate easy replacement of original music.
To replace original music, insert the following named files into this folder

"menumix1"			<-- Mainmenu music
"marimbad 2"		<-- Laptop music
"nothing A"			<-- Tactical with nothing special going on
"nothing B"
"nothing C"
"nothing D"
"tensor A"			<-- Tactical, enemy present
"tensor B"
"tensor C"
"triumph"
"death"
"battle A"			<-- Tactical, enemy present and visible
"tensor B"			<-- This file is also used as battle music
"creepy"			<-- Tactical, creatures present
"creature battle"	<-- Tactical, creatures present and visible
