Every little detail at the Super Bowl is heightened, hyped and promoted during the two weeks before the game.

In the regular season, most folks watch highlights at halftime. At the Super Bowl, the halftime show is one of the most anticipated concerts of the year.

In the regular season, the pregame show lasts an hour or so and includes some mildly entertaining content or interesting interviews. Before the Super Bowl, it could last up to seven hours.

And don't get me started on the commercials.

That leads us to the national anthem. In the regular season—and even the playoffs—only the folks at the game generally take in the performance of the national anthem. At the Super Bowl, it's a huge deal and even has prop bets speculating on the performance time of the song.

Yeah, you read that right. People bet on the national anthem. 

This year's performer is the talented Alicia Keys, who has promised a special rendition of the song. While talking to Jerry Penacoli of EXTRA about performing the national anthem, she winked and said, “Wait till you hear this one," then added, "You’ll see. I’m gonna do it in a way that only I can do."

Generally, the best renditions of the national anthem are simple and elegant, as the performer stays true to the original but subtly adds their own personality into the performance.

It also helps if you are Whitney Houston.

Oh, and did I mention the prop bets? Yes, it's true, you can actually bet on the song's duration. Here are a few of the props Bovada.lv is offering (h/t Fox Sports):

Choose wisely, friends.
