I’d set up a website meant for the whole world where anyone could vote for their favourite song of the moment. Then, everyday, I’d choose a country randomly and pick the domestic song that would border the closest on those two requirements : the most voted for in this country & the less voted for in all the other countries.
And that’s when my power would come into force. Once a day, in the air, in each country (with regards for GMT, thus respecting night times), I’d move several huge blimps fully equipped with insanely powerful speakers, and let everyone discover that song (meaning never two times the same song). I’d call it the “You Teh Tell !” podcast.
Btw, always on top of the website would stand a poll, where everyone could vote for me to continue or stop or start again, anytime.
What would you do if you had to cosplay for New Year’s eve ?
