Hello
Be sure to read the README in "mods" in order to get extra info if you get stuck somewhere.

If you don't have a code editing software, be sure to right-click any mxl, "open with">"Choose another app" check off "always use this app", and click "notepad".

Once you're done editing, be sure to save (ctrl+s) and then enable the mod in-game by accessing the mod menu in the bottom right hand corner.

in order to add and remove music, you must modify these sections of the script, in sound_library.xml found under the "sounds" folder:

<!-- MUSIC -->
	<Sound ID="music_main_menu" channel="music" stream="true">
		<!-- note that this has some hardcoded time offsets for where to start in the main menu -->
		<Path name="data/sounds/music/mainmenu1.ogg"/>
	</Sound>

	<!-- in case of streamed sounds, 'preload' means that only their headers are parsed, they won't be entirely preloaded -->
	<Sound ID="music_ingame" channel="music" stream="true" preload="true">
		<Path name="data/sounds/music/ingame1.ogg"/>
		<Path name="data/sounds/custom_modded_music/cool_track.ogg"/>
	</Sound>

	<Sound ID="music_win" channel="music" stream="true">
