There's no reason Philly alternative hip-hop duo [artist id="3482242"]Chiddy Bang[/artist] should be afraid of a matronly 68-year-old standards singer. But, on the eve of the 2011 Woodie Awards in Austin, Texas, "Chiddy" Anamege and Noah "Xaphoon Jones" Beresin are sweatin' the competition in the Best Video category thanks to "Barbra Streisand."

The Babs they fear is not, of course, the "Yentl" star herself, but the insanely catchy song that borrows her name from DJ duo [artist id="3494237"]Duck Sauce[/artist], whose video features cameos from Kanye West, the Roots, Chromeo and Vampire Weekend.

"I think the biggest competitor in our category is gonna be 'Barbra Streisand,' " Beresin told MTV News about the video that accompanies the poppy dance track. "That video is crazy. It's like, 'Oh man, we're friends with this famous guy' ... They've got so many cameos, and it's shot really well."

While Bang's clever clip for the MGMT-sampling "Opposite of Adults" has its own merits, not limited to their cartoonishly gigantic heads, they've got plenty of stiff competition in the category from some other stellar clips, as well. They're up against the Black Keys' lauded schoolyard beat down in "Tighten Up," Vampire Weekend's equally cameo-heavy (Jake Gyllenhaal, Lil Jon, RZA and Joe Jonas) "Giving Up the Gun" tennis throwdown and the Gorillaz' Bruce Willis-starring desert death race, "Stylo."

In fact, theirs is one of the only clips in that bunch that doesn't have a marquee cameo, so maybe their lo-fi indie sensibility will win the day after all.

Performers at this year's show, hosted by Donald Glover, include the Foo Fighters, Wiz Khalifa, Odd Future, Sleigh Bells and Two Door Cinema Club.

As in previous years, Woodie winners will be determined by fan voting. Voting in most Woodie categories closed Tuesday (March 15), but votes will continue to be counted in the Breaking Woodie category right up until the show.

The 2011 mtvU Woodie Awards will air live on MTV, MTV2 and mtvU from the South by Southwest Music Festival in Austin, Texas, on Wednesday, March 16, at midnight ET/PT.
