Sync Windows Media Player with Huawei android

Maybe the easiest way of getting music from your PC to your mobile is by using Windows Media Player. But I could not find out how to "sync" my PC with my Huawei (android) phone. There are so many helpful hints on the internet, but if they can be applied depends on what mobile you have. By shear luck, I found the solution. If you have a Huawei, this solution should work for you too. Please bear with the video, since this is my first video to be uploaded.
