Song in loop

The biggest advantage of listening to songs on a pc instead of cassette player/CD player is that you can repeatedly listen to the same song without having to rewind each time. A time comes when you unknowingly start singing it to yourself in mind. In a passing moment you sing some line of the song without realizing or try to give rhythm on your table. The difference between singing the line to yourself or aloud is blurred for that moment. Somebody around you gives you a puzzled look. You are not in a mood to explain. You smile or completely ignore the person.
Today's song in loop for me was:

Ek parvaaz dhikhayi dee hai
Teree aavaaj sunaayi dee hai
