Did somebody happen to listen to the beats in O Saya it starts just like the train and then slowly accelerates just like the train. just before AR starts singing the beat is like the train passing through a bridge and in some places like it changes tracks and almost then song changes its track. The whole song is still balanced with that beats. This is not new of AR who already had given a new dimension for the beats sounding like train sound. It all begun with Chiku buku raile which had typical. What followed in Chaiyya Chaiyya was another new form. And now its O Saya. Here the metal is more genuinely sounding to the train.
