Have multiple sounds emit from one entity?

So I’ve been using self:EmitSound but I’ve gone across one problem, only one sound can play at once and the others are stopped. This is on a SWEP where a song plays when you have it deployed (Don’t ask) but whenever I shoot the song is stopped from playing. So can anyone help?

Use a different soundchan parameter in emitsound

Entity:EmitSound
fifth param

Thanks
