Is it possible to play a specific id within a brick?

I'm not sure if you can do this but can you have a music player which plays a specific music id within an area of a brick only. I know that you can do this with sound environments that have a script preset with the id but I'm not sure if there's a way to play a id within a game. This is not a request I just wanna know if its possible, im fairly new to scripting. I have all the scripts to play the actual id I'm just not sure if or how I can contain it within a brick.

local SG = game:GetService("StarterGui")
local P = game:GetService("Players")
local B = game.Workspace:WaitForChild("Radio") or game.Workspace:FindFirstChild("Radio")
local Debounce = false

P.PlayerAdded:connect(function(player)
    if player ~= nil and Debounce == false then
        Debounce = true
        if B and Debounce == true then 
            if B.Brain.MainWall:FindFirstChild("RadioSurfaceGui") then -- 
                local Gui = B.Brain.MainWall:FindFirstChild("RadioSurfaceGui")
                if Gui then
                    Gui.Parent = SG
                    if SG:FindFirstChild("RadioJSurfaceGui") then
                        local RealGui = SG:FindFirstChild("RadioSurfaceGui")
                        if RealGui then
                            RealGui.Adornee = B.Brain.MainWall
                            wait()
                            Debounce = false
                        end
                    end
                end
            else
                if not B.Brain.MainWall:FindFirstChild("DRadioSurfaceGui") then
                    warn("Don't move the SurfaceGui into StarterGui!")
                end
            end
        end
    end
end)

Script to playthe music

local TB = script.Parent.Parent.TopBox
local BP = game.Workspace.Radio
local Pattern = "^%d+$"

script.Parent.MouseButton1Click:connect(function()
    if TB.Text:match(Pattern) then
        BP.Sound.SoundId = "http://www.roblox.com/asset/?id=" .. TB.Text
        BP.Sound:Play()
        wait(1)
        TB.ClearTextOnFocus = true
        TB.Text = "Click here, type an Audio ID, then click Enter"
        TB.LocalScript.Disabled = true
        wait()
        TB.LocalScript.Disabled = false
    else
        if not TB.Text:match(Pattern) then
            TB.ClearTextOnFocus = true
            TB.Text = "Invalid Audio ID"
            wait(1.5)
            TB.Text = "Click here, type an Audio ID, then click Enter"
        end
    end
end)

local BP = game.Workspace.Radio


script.Parent.MouseButton1Click:connect(function()
BP.Sound:Stop()
BP.Sound1:Stop()
