Turns out the song is the choice of Hill's young daughter, who is a big fan of the movie "Despicable Me 2," whose soundtrack features the song.
"She said, 'Daddy, this could be our song,'" Hill said. "Then my wife said, 'You should use that music when you come up,' and my daughter got all excited about it. How could I say no to her?"
Truth is the song is a great fit for Hill, who is one of the more content people you will ever meet.
"What's not to be happy about?" Hill said. "I'm married to my best friend, I have an awesome family and I get to come play baseball every day."
