Continuous background music with winsound module

Question

So, I have been working on this game called Space Invader. Everything is doing great except for one thing which is the sound. As in the below code, I've imported winsound module and it is not doing well. When I fire the bullet it makes the fire noise which I wanted but the problem is that I've also added background music, and whenever I hit fire it stops the background music and starts making fire noises until it hits the target. I want background music to run continuously. I've also seen many Youtube videos but couldn't get any help. Can anyone tell me the mistake which I've made in the below code?
