Youtube please design a repeat or loop button!!

Exams are around corner and music keeps me alive. So here I am doodling a small idea this time.

Listening to Linkin Park's latest ablum on Youtube recharges my soul n body to keep the midnight oil burning; but I realised Youtube could improve features tremendously by just adding a video looping button or a repeat button. That button would make life so much more easier, so please Youtube team make the button.
