This is not a game. This is probably the song everyone will have playing inside his head once he hears it. Seriously, i was listening to Arrow three days ago, and some villain began to whistle a part of the song. ITS BEEN THREE DAYS I HAVE THIS SONG PLAYING IN LOOP IN MY HEAD!!!!!! And the only way I have to... well... feel satisfied (if you ever had a song looping in your head, you know what i mean) is to listen at different version of this song... METAL, CLASSIC, ROCK SYNTHETISED, ORCHESTRA, ACCAPELLA EVERY SINGLE VERSION.... AND IM STILL NOT SATISFIED ENOUGH AFTER THREE DAMN DAYS!!!! A CURE PLEEEEEEEASE!!!!
