How do I get a random sound by Roblox?

I want to get a random sound from Roblox, to make some sort of radio. Like play a random sound from the hundreds of audio that ROBLOX has uploaded. Putting in all of the APM music that Roblox has uploaded in a table would be impossible, and I'm sure there's a way to automate this.

local sound = script.Parent
while true do
    local randomAsset = "http://www.roblox.com/asset/?id=" .. math.random(1, 999999999)
    sound.SoundID = randomAsset
    wait(1)
end

This takes forever, but theoretically works. Hopefully it can be made faster.

local mps = game:GetService("MarketplaceService") -- Get the MarketplaceService
local sound = script.Parent

while true do
	local randomAssetId = math.random(1, 999999999) -- Get the Id first so that we have it seperately from the url
	local randomAssetUrl = "http://www.roblox.com/asset/?id=" .. randomAssetId -- Does the normal thing, but with our variable instead of making up the id then and there
	local musicId = "rbxassetid://" .. randomAssetId -- The id for the audio object
	
	wait() -- Wait until the asset picking is done, not sure if this is necessary

	local details = mps:GetProductInfo(randomAssetId) or false -- Get the details, or set to false if invalid id
	if details then -- Check if valid object (details exist)
		print("Valid Asset")
		if details.AssetTypeId == Enum.AssetType.Audio then -- Check if the asset is an audio
			print("Audio")
			if details.Creator.Id == 1 then -- Check if the sound is uploaded by roblox (using id for if the ROBLOX account is ever renamed Roblox or something else)
				sound.SoundId = randomAssetUrl -- Finally set the SoundId
				print("Roblox Audio")
			end
		end
	end
	wait()
end

But that takes forever. I'd recommend putting some of your favorite APM tracks into a folder and picking random tracks from that folder.
