Sound Glitches On Death?

Problem

Every time the player spawns, if Stage.Value is > 1, the appropriate song will not play.

Suggestions

Given how you name your sounds, it would be best if these were stored in a table so you can iterate through it and index them neatly. As a plus, you can get rid of those ugly redundant if-statements.

Solution

Sounds = script:WaitForChild'SongFolder'

local Songs = {
Sounds:WaitForChild'Sound1',
Sounds:WaitForChild'Sound2',
Sounds:WaitForChild'Sound3',
Sounds:WaitForChild'Sound4'
}

Player = game.Players.LocalPlayer
PlayerGui = Player.PlayerGui
Leaderstats = Player:WaitForChild'leaderstats'
Stage = Leaderstats:WaitForChild'Stage'

function PlaySound(id) -- Stops all the songs that are currently playing, then plays the sound.
    for _, v in pairs(Songs) do
        v:Stop()
    end
    Songs[id]:Play()
end

PlaySound(Stage.Value) -- play the appropriate song every time the player spawns
Stage.Changed:connect(function(NewValue) -- whenever the stage changes, play the appropriate song.
    PlaySound(NewValue)
end)

Sounds = script:WaitForChild'SongFolder'

Player = game.Players.LocalPlayer
PlayerGui = Player.PlayerGui
Leaderstats = Player:WaitForChild'leaderstats'
Stage = Leaderstats:WaitForChild'Stage'

Song1 = Sounds:WaitForChild'Sound1'
Song2 = Sounds:WaitForChild'Sound2'
Song3 = Sounds:WaitForChild'Sound3'
Song4 = Sounds:WaitForChild'Sound4'

if Stage.Value == 1 and Song1.IsPlaying ~= true then
Song1:Play()
end
 Stage.Changed:connect(function(NewValue)
if NewValue == 2 and Song2.IsPlaying ~= true then
Song2:Play()
Song1:Stop()
 end
end)
Stage.Changed:connect(function(NewValue)
if NewValue == 3 and Song3.IsPlaying ~= true then
Song3:Play()
Song2:Stop() 
end
end)

Stage.Changed:connect(function(NewValue)
if NewValue == 4 and Song4.IsPlaying ~= true then
Song4:Play()
Song3:Stop()
end
end)
if
game.Players:FindFirstChilden():LoadCharacter() == true and song1 or song2 or song3 or song4.IsPlaying == true then
for i,v = 1,4 
song[i,v]:stop()
end
end

Tell me if it works, didn't test it in studio.
