Complaining about lame theme nights on is kind of like griping about that know-nothing dork in your office who always wins the Final Four pool: go ahead, but it's just gonna keep happening the same way every year.

So far we've been spared disco night and haven't had to sit through songs of inspiration or an evening of Rat Pack retreads. Which means that Wednesday's (April 10) "A Song I Wish I Had Written" night could either be amazing or yet another stroll down cheddar lane.

The top six — Lazaro Arbos, Janelle Arthur, Candice Glover, Kree Harrison, Amber Holcomb and Angie Miller — will each sing twice (the theme for the other song had not been revealed at press time.) What songs do they wish they'd come up with? We have no idea, but that didn't stop us from guessing. (Keep in mind, we did this without peeking at each other's choices, that's how predictable this season is.)

Lazaro Arbos: Season 12's weakest link proved he at least kind of gets Queen last week, but he can't go to that well so soon again. Maybe he'll travel the Michael Jackson route and milk the emotional/inspirational vote one more time with "Man in the Mirror." Kaufman

He wishes he wrote every single song in the Mariah Carey back catalog, so he'll do something from her. Which one? Who cares. Then again, he had success with Queen last week, so maybe he does "The Show Must Go On," which is ironic since there's no possible way said show continues on past ...

Well, it's come down to this: We've made it to the championship game of MTV's Musical March Madness ... after surviving a Final Four that spanned six days, several technical failures and one official re-start.

It'll be Ed Sheeran battling it out against Thirty Seconds To Mars in a title-game tilt that's sure to be one for the ages, especially given everything we've witnessed so far. Two bands remain out of our field of 64, but only one will be crowned the 2013 MMM Champion ... and it'll be up to you to determine who comes out on top. Voting in our championship game is now underway, and polls will close Friday, April 12 at noon ET.

Oh, and just like we've done in previous years, to build suspense, we're keeping the voting results secret until Friday afternoon, when we'll crown our champ!

And while we're not sure who's going to win MMM, there's one thing we do know: it won't be prohibitive favorites Tokio Hotel. They were knocked off by Sheeran in one of the most hotly-contested (and downright nasty) Final Four battles in tournament history, as fans of both bands crashed a pair of polling sites, forced us to implement a "one vote per hour" contingency plan, and basically called each other — and us — every mean name in the books. From the moment we re-launched the polls on Monday, this one went back-and-forth, first with Sheeran surging to a lead, then TH fighting back and holding an edge for most ...

When you're an artist as prolific as Jay-Z, you're often faced with the task of having to outdo yourself. Last year Hov set the bar pretty high when he curated, headlined and shockingly brought out G.O.O.D. Music at the Budweiser Made in America in Philadelphia. Topping that is no easy task, but luckily for Jay, he knows a few folks.

On Wednesday (April 10), after an interactive announcement on the music-streaming site Spotify, Budweiser revealed that Beyoncé will headline the first day of the two-day festival on August 31 and Nine Inch Nails will hold things down September 1.

"One of the things on our mind was how do you top it? How do you go into year two and make sure that you're continuing to live up to the ideals of Budweiser Made in America," Paul Chibe, vice president of U.S. marketing at Anheuser-Busch, told MTV News. "Jay really did an amazing job curating the lineup."

Aside from pulling strings with the Mrs., Hov helped to gather a robust and diverse lineup that will play throughout the weekend. 2 Chainz, A$AP Rocky, Kendrick Lamar, Schoolboy Q, Jay Rock, Ab-Soul, Wiz Khalifa, Public Enemy and Macklemore & Ryan Lewis will hold it down for the hip-hop set.

Queens of the Stone Age, Haim, Empire of the Sun, Imagine Dragons, Walk the Moon and Phoenix will give the festival its rock edge, while Deadmau5, Calvin Harris and Wolfgang Gartner will keep fans dancing. Miguel and Solange will also add some love to the event.

The public will be able ...

The first extended scene from is coming this Sunday exclusively at the 2013 MTV Movie Awards, but you can get a snippet of the action ahead of time — that is, if fans band together online to power Tony Stark's arc reactor.

Using the Twitter hashtag #UnlockIronMan, fans can fuel Tony's power source at MTV.com, unlocking a sneak peek of the "Iron Man 3" extended scene that will premiere in its entirety during the Movie Awards at 9 p.m. Sunday. Iron Men (and Women) are encouraged to tweet as often as possible and check back regularly to see how quickly the reactor reaches full power, at which point MTV will unveil a snippet of footage from that exclusive scene.

"Iron Man 3" wraps up a trilogy of films starring Robert Downey Jr. as Tony Stark, a billionaire industrialist whose search for a remedy for his ailing heart led to the construction of a superhuman suit of armor. In the latest film, which is set for release May 3, Stark finds his business and personal lives threatened by an unknown adversary with seemingly bottomless resources. As he fights to keep his company afloat and his friends safe, Stark must come to terms with what made him the hero he is today — the suit of armor he wears or the man inside it?

Meanwhile, Iron Man is but one of the heroes being honored at the MTV Movie Awards: "Marvel's The Avengers," featuring Stark and several of his superpowered colleagues, was nominated for ...
