Animation Code not loading fast enough?

Repost

So I need some help with efficiency problems with a "Play Animation on click" script. It's a really simple part-click script that changes the animation of a NPC to another random animation. The real issue is that there is a random delay that appears trying to load the next animation. What I need it to do is let the player be able to spam the button, increase the score and change the animations smoothly.

What I think it is, it's something to do with the single wait(.1) I have at the bottom of the code, but I have no idea if it's really the case or how to change it to something better. Also I doubt my animations have delays in them since its 5 with the same timeline lengths, priority and KeyFrames.

local runService = game:GetService("RunService")

local starterGui = game:GetService('StarterGui')
starterGui:SetCore("TopbarEnabled", false)
local scoreValue = script:FindFirstChild("Score")

game.Players.PlayerAdded:connect(function(player)
    player.CharacterAdded:connect(function(character)

        if not character:FindFirstChild("Humanoid") then return end
        local humanoid = character:WaitForChild("Humanoid")
        humanoid.WalkSpeed = 0

        --SETUP OUR ANIMATIONS
        local animationTable = {887079940,887088637,887093321,887096360,887101694}
        local clickOnMe = game:GetService("Workspace").ClickOnMe
        local Humanoid = game.Workspace.Noob:WaitForChild("Humanoid")
        local animation = Instance.new("Animation", game.Workspace.Noob)
        local previousAnimation;

        --LOAD IDLE ANIMATION
        animation.AnimationId = "http://www.roblox.com/Asset?ID=887061813"
        local idleAnimationTrack = Humanoid:LoadAnimation(animation)       
        idleAnimationTrack:Play()

        --LETS ANIMATE THIS
        local function buttonClicked(player)
            local randomAnimation = math.random(1, #animationTable)
            if randomAnimation == previousAnimation then return end
                previousAnimation = randomAnimation
                print("Running Animation #"..randomAnimation)  
                animation.AnimationId = "http://www.roblox.com/Asset?ID="..animationTable[randomAnimation]
                local animTrack = Humanoid:LoadAnimation(animation)
                scoreValue.Value = scoreValue.Value + 1        
                animTrack:Play()
                wait(.1)
            end
    end)
end)

I'm sure the code will let you know what's wrong but if you need more info then comment.
