I have a countdown plugin, but I want to add a song

Lets say when a new round (Before choosing infection mode, nemesis, etc.) and there is a countdown so I want to have a music with it please help.
that's the SMA code.

#pragma compress 1



#include <amxmodx>



new count



public plugin_init() register_event("HLTV", "event_roundstart", "a", "1=0", "2=0")



public plugin_precache() {

precache_sound("xman2030/task/1.wav")

precache_sound("xman2030/task/2.wav")

precache_sound("xman2030/task/3.wav")

precache_sound("xman2030/task/4.wav")

precache_sound("xman2030/task/5.wav")

precache_sound("xman2030/task/6.wav")

precache_sound("xman2030/task/7.wav")

precache_sound("xman2030/task/8.wav")

precache_sound("xman2030/task/9.wav")

precache_sound("xman2030/task/10.wav")

}



public event_roundstart() {

set_task(9.0, "start_countdown", 12345678903)



count = 11

}



public start_countdown() {

remove_task(12345678903)

remove_task(12345678904)

set_task(1.0, "countdown", 12345678904)

}



public countdown() {

if(count == 0) client_print(0, print_center, "")

if(count > 0) {

if(count < 11) client_cmd(0, "spk xman2030/task/%d", count)

set_dhudmessage(random_num(1, 255), random_num(1, 255), random_num(1, 255), -1.0, 0.28, 2, 0.02, 1.0, 0.01, 0.1)

show_dhudmessage(0, "Zombie attack starts in %d seconds", count)

}

count = count - 1

if(count >= 0) set_task(1.0, "countdown", 12345678904)

}
