SUGGESTION:
The GM should be able to toggle a 'Usable' button next to each sound/music in the game. When a player goes to their media player playlist, each of those tracks should list a 'Macro Friendly' name. (Like an autogenerated #TRACK132) which can then be added to a macro.
This way, when a player has GM permission to add the #TRACK148 (ATTACK SOUND) to their macro. So that when they attack, it makes the sound.
