Why did farmville change?

well when i played it a long time ago, it had that catchy music and you could harvest and plow it was brighter and you had normal wooden fences. but just now i decided to play it again and it is all american style, ya know? like brittish and the music is awful. its like all olden day stuff. ughhh i cant explain.! so go check it your self if u play farmville. anyway thanks :)
