Show how many are listening to the same song

[polterbyte]

A button beside the song being played that, upon being clicked, displays how many people are listening to the same song in the same city, the same country, and in the world. For the world, a small list showing the top-3 or top-5 countries, with their respective percentages of people listening. No need to show anything else, just quantities, not anything else.

I'm pretty sure many of the songs I listen to are being listened by less than 100 people around the world, or even less. Knowing this for sure and seeing the countries where they come from would be very neat.
