Maybe I'm just paranoid, but...
I borrowed a game called Evolution Worlds around 2004. When I entered the town shop, I was surprised to find myself humming every note of the music without having ever rented the game before. I concluded that the song must have been copied from something else, but I could never put my finger on what.
Here is the song in game: http://www.youtube.com/watch?v=fC8e0hztFOk
I thought for a while that maybe it was the Hampsterdance/Robin Hood opening theme, but it's not similar enough for me to hum the whole thing on the first try. I get the feeling it's either a children's song or a commercial jingle. Also, I feel like there should be a short bridge before the tune repeats.
Does anyone else recognize this simple little tune!? It's driving me crazy!
