How do I make a random audio play?

Assign each music track a number then generate a random number and when the number is selected use that number to play the track assigned said number

random number generator taken from roblox wiki

for _ = 1,1 do
    print(math.random(10))
    wait(1)
end

EXAMPLE SCRIPT

local 1 = track1
local 2 = track2
local 3 = track3

local track = (math.random(3)) -- put number of tracks where 3 is

it would need some work to get it to work :D but it is the basic idea

local musicids={123456,123456,1234556} --Change these to the music ids you want to play, feel free to add some music
function PickRandomFrom(tab)
return tab[math.random(1,#tab)]
end
local id=PickRandomFrom(musicids)
local music=Instance.new("Sound",game.Workspace)
music.SoundId=id --I'm not sure if it's called SoundId, probably something else
music:Play()
