Thanks!
Another guy also mentioned the sound and I gave it a go but I failed.
I tried adding a mute button but it needs a lot more work than it should. Also, If I muted the game, all the sfx would mute too. And I decided not to bother with it. The music and sfx are critical for the game and I spend about 15% of the game's development for the sound, so If anyone wants to kill the music, they should do it from the Windows sound options.
Look into how to create new audio buses for the game and route all sfx to a sfx bus and all music to a music bus, that way you can mute or alter the volume separately. Like some people might want a low volume on the music but keep the sfx high. Though how difficult this is for the engine you are using I don't know. I haven't experimented with volume sliders or such yet but in Dragonslide I made two separate channels to mute music and sfx because I got a comment wishing for the option.
