Can someone help me with my Song Player Gui script?

When I click a song, it plays. When i try to click multiple songs it plays the song but the script doesn't work correctly and deletes the previous song before stopping it. Here is the script!:

-----------------------------------------------

local player = script.Parent.Parent.Parent.Parent

local stopp = M.StopPic
local stop = M.Stop

local next = M.Next
local less = M.Less
local more = M.More
local drag = M.Dragger
local dragtext = M.DragText

local musiclist = {}
local musicmodel = script.Parent.Parent.Music
local music = musicmodel:children()
for i,v in pairs(music) do
v.Looped = false
v.PlayOnRemove = false
table.insert(musiclist,v:clone())
end
musicmodel:remove()
local musiclistbuttons = {}
for i,v in pairs(musiclist) do
local ng = Instance.new("TextButton",M)
ng.Position = UDim2.new(0, 0, 0, 20) + UDim2.new(0,0,0,13*i)
ng.Size = UDim2.new(0, 200, 0, 13)
ng.BackgroundTransparency = 1
ng.BackgroundColor3 = Color3.new(0/255,0/255,0/255)

ng.Text = v.Name
ng.Name = v.Name

ng.MouseButton1Click:connect(function()
if ng.BackgroundTransparency == 1 then
changesong(musiclist[i])
end
end)

end
