Singing brick

[toaster468]

ENT.Type   = "anim"
ENT.Base                = "base_anim"
ENT.PrintName           = "Singing Brick"
ENT.RenderGroup         = RENDERGROUP_TRANSLUCENT

function ENT:Initialize()

  
    if ( SERVER ) then
        self.Entity:SetModel( "models/props_junk/CinderBlock01a.mdl" )
        
        self.Entity:PhysicsInit( SOLID_VPHYSICS )    
    end
    
end

function ENT:Use( activator, caller )
    
    if ( activator:IsPlayer()) then
       
        self:EmitSound("team fortress 2\tf\sound\ui\tv_tune3.mp3", 500, 200)

    end
    
end

function ENT:SpawnFunction( ply, tr )

    if ( !tr.Hit ) then return end
    
    local SpawnPos = tr.HitPos + tr.HitNormal
    
    local ent = ents.Create( ClassName )
        ent:SetPos( SpawnPos )
    ent:Spawn()
    ent:Activate()
    
    return ent
    

OK so i have what i want so far but what i have been trying hasn't worked. I want this entity to do just its name, sing.

in my entity use function I tried making it emit a sound i provided in the parameters which is a tf2 show tune.
But when I click e on it i get 4 stack overflow errors and it brings me immediately back to the GMod start menu. Any help would be appreciated.
