Sounds not playing correctly.

Alright, in my SWEP, I am planning on music playing when you Deploy it.
My current code is this:
[lua]function SWEP:Deploy()

When I begin Gmod, the SWEP works correctly for the most part (ammo still isn’t taken), but I get a LUA error saying that the Sound file failed to load. I don’t know what causes this, is there any way to fix it? This also happens with another sound.

EmitSound is relative to the sound directory. It would just be /Weapons/zarathustra.mp3, not /sound.

Oh, okay. I’ll fix that. Thanks!
