This week, even as everything was going to hell at high speed, I fell in love with a map of geographical musical bubbles, on pudding.cool.

A musical bubble is the geographical area where the same song is a number one hit. The interactive map showed how one song may be no. 1 in and around Bombay, but completely different songs ruled the charts in say, Mysore or Chhattisgarh. And Dhaka’s musical bubble might look more like Bombay’s than say, Indore’s. Some years ago, while tracing the history of Munni Badnam Hui for a film on copyright, I discovered that different places had completely different hit versions of this hit song, mini musical bubbles.
