Request Song Play When Attacking Raid Boss

[synthe]

Hi guys,

 

I know this is possible, Did it before years ago but forget the method.

I've made a custom boss. Now when people attack this mob, I want a "battle song" to be played. 

But not a default song, a custom song which I encrypt ....

this one:  

 

 

How can I do this? I know I have to decrypt the song client side
