How to make different sound environments?

local areas = {
    [1]= {
        Name = "Town",
        Center = Vector3.new(0,0,0),
        Music = "13333337"
    },
    [2] = {
        Name = "Toilet",
        Center = Vector3.new(50,0,0),
        Music = "13333337"
    },
    [3] = {
        Name = "Wilderness",
        Center = Vector3.new(0,0,50),
        Music = "13333337"
    }
}

local me = game.Players.LocalPlayer
local sound = Instance.new("Sound")
local currentArea = nil

local function getClosestArea()

    local closestArea = 1
    local minimumDistance = me:DistanceFromCharacter(area[1])


    for i,area in pairs (areas) do
        local distance = me:DistanceFromCharacter(area.Center)
        if distance < minimumDistance then
            minimumDistance = distance
            closestArea = i
        end
    end

    return closestArea
end

while wait(1) do
    local closestArea = getClosestsArea()

    areaData = areas[closestArea]

    if currentArea ~= areaData.Name then
        currentArea = areaData.Name
        sound:Stop()
        sound.SoundId = "rbxassetid://"..areaData.Music
        sound:Play()
    end
end
