If you've played the spore cell stage I am sure you have heard something play in that stage similar to this. I recreated it on Google's music maker, and it turns on to be pretty good.
~Images found on Google. ~The game is called Spore, it's a game where you play as a creature or group of creatures to achieve intelligence and the ability to explore space. You are able to edit the features of your creature too. You start with the Cell Stage. then Creature Stage then Tribal Stage then Civilization Stage then Space and final stage. this stage is impossible to beat too, to do it, you have to conquer the entire galaxy.
