Crazy song I don't know the title

[denis2000]

Hi everyone,

There is a song I heard, but I have no idea what it is. It's a girl singing, there is a kind of banjo and other crazy instrument. It's very happy and the girl is singing something like:

So if you think I love (or want) you, you got (or better) to change your mind...

And the music goes: dada dada dada daaaa dada, dada dada daaaa da

I really don't know much, but It a very nice song,

If anybody can help, I would love it

Denis
