All we love to watch videos (mp4) or listen music (mp3) on YouTube player but sometimes YouTube application freezes, stop responding, works slowly, you got "connection problem" message or you have other problems.
What are you doing?
You go to settings, search for Youtube and then stop it! It takes a lof of time!
Use "Restart Youtube" application to quick restart Youtube and continue search for music, use playlist or watch your favorite, top rated videos!
