function getId()
	if string.sub(Music.SoundId,1,31) == "http://www.roblox.com/asset/?id=" then

Error: 17:09:27.095 - Unable to cast string to int64 17:09:27.097 - Stack Begin 17:09:27.098 - Script 'Players.Professional_Lua.PlayerGui.Main.Main', Line 40 17:09:27.098 - Stack End

The function getId() is returning the id as string. The parameters for GetProductInfo requires int64 (numbers), so you'll have to convert the string using tonumber(string).

Music.Changed:Connect(function()
    if Music.Playing ~= false then
        local Id = getId()
        local Info = MarketplaceService:GetProductInfo(tonumber(id))
        SetGuiText(Info.Name,Info.Creator.Name)
    end
    if Music.TimePosition > 0 then
        Bar:TweenSize(UDim2.new(Music.TimePosition/Music.TimeLength,0,0,4),"Linear","Out",true,0.5)
    end
end)
