OK, I chose who my best answer was, so why didn't they get it, why did someone Else's incorrect answer get it?

First, the song is not called "American Triolagy", it is called "the battle hymn of the republic". So why did the one who called it American Triolagy get voted as my best answer. Thats not who I voted for. Whoever said the title and told me to go to wikpedia or whatever was absolutly correct and it was very helpful. that other guy didn't know what he was talking about and he should not have even attempted to answer my question, but ya'll voted him my best answer. What!?
