It's that time of year again!

This Sunday, the world will tune in to the Super Bowl to check out the show-stopping performances, hilarious new commercials, and if you're anything like us, possibly catch a minute or two of football while passing the TV on their way to the snack table.

Everyone's always so geared up for the halftime performance, but what about the lesser-celebrated performances that come before every Super Bowl? The singing of America's national anthem, "The Star Spangled Banner"!

To honor America and gear up for this Sunday's Super Bowl, check out some of the game's most iconic national anthem moments.

Whitney Houston

It's safe to assume nobody will ever top Whitney's jaw-dropping performance at Tampa Stadium in 1991, which is still regarded as one of the best renditions of "The Star Spangled Banner" in history. Rest in peace, queen!

Cher

Cher sang in 1999 at Miami's Pro Player Stadium, riding high on the recent success of "Believe"!

Jennifer Hudson

Leave it to the incomparable Jennifer Hudson to turn the national anthem into one of the hottest breakup songs. Her soulful rendition above is from the 2009 game at Raymond James Stadium in Tampa.

Jordin Sparks

The unofficial Queen of R&B at the University of Phoenix Stadium in 2008 — officially the one who delivered the best facial expressions.

Kelly Clarkson

Kelly kicked things off in 2012 at Lucas Oil Stadium in Indianapolis. She was clearly going through an awesome bangs phase.

Beyoncé

Hometown girl Beyoncé sang her face off at Houston's Reliant Stadium in 2004, exactly 10 years before she returned to slay the halftime show.

Dixie Chicks

Dixie Chicks were surprisingly well received by San Diego in 2003, given those politically charged comments they made about George W. Bush months before.

Mariah Carey

Wait for that note at the end of Mariah's 2002 performance at New Orleans' Superdome. Killed it!

Vanessa Williams

No tea no shade, but Vanessa Williams actually had one of the best flyovers on this list. Here's her performance at the Sun Devil Stadium in Tempe, Arizona in 1996.
