If round one of MTV's Musical March Madness was marked by shocking upsets— we bid adieu to #1 seeds the Foo Fighters, Mumford & Sons and the Black Keys, not to mention U2, the Red Hot Chili Peppers, Maroon 5, Foster the People and Fun. — well, then, round two is shaping up to be a return to normalcy (shout out to Warren G. Harding!)

That's because, with polls in all second-round matchups set to close Sunday at midnight ET, it's looking very much like the favorites will flex their collective muscles and advance to the Sweet 16, as Evanescence, Paramore, My Chemical Romance and Green Day all hold commanding leads over lesser-seeded opponents.

Then again, as history has proven time and time again, anything can happen in MMM ... and there are plenty of potential upsets still brewing. (Blink-182, we're looking at you.) So as we prepare to close the books on the second round — and make arrangements for the Sweet 16 — here's an updated look at the action!

In the Midwest, where the highest remaining seed is #5 MCR (currently blasting #13 Modest Mouse), the battle between #9 Rise Against! and #16 AWOLNATION looks like it's headed down to the wire, with RA! currently holding a slim lead. The same can also be said about the #11 Chevelle/#15 Five Finger Death Punch tilt (it's Chevelle plus 4,000 at the moment) and the #7 Metallica/#15 Sum 41 matchup, where the Canadian crushers appear poised to once again advance to the round of 16.

In the West, #16 James Durbin, fresh off his scalping of #1 Foo Fighters, holds a commanding lead over #8 Best Coast, defending MMM champs Green Day are crushing #13 Lana Del Rey and #15 Panic! at the Disco currently lead #10 No Doubt, though the gap is closing by the minute. But far and away, the tightest matchup is #3 Blink-182 vs. #11 Adam Lambert, where, thanks to the undying support of his Glambert Nation, it's Adam by a bushel, which could mean that Blink are headed for their earliest MMM exit ever. Like we said, there's still time to mount a comeback, but the hour is growing late.

Over in the East, #10 Coheed and Cambria and #12 Tokio Hotel appear headed for a showdown in the Elite Eight, as they're both blasting their second-round opponents, and, judging by the way things are shaping up, neither would face much of a challenge in the Sweet 16. As it stands right now, Coheed would draw #11 Semi Precious Weapons, who, thanks to the efforts of frontman Justin Tranter's mom, are pulling away from #3 Florence and the Machine, and Tokio would face off against #8 Radiohead ... though the erudite rockers are getting all they can handle from upset-minded F---ed Up, in what's shaping up to be the closest second-round contest.

And finally, in the South, lone-remaining #1 Evanescence are living up to the advanced billing, throttling #9 Dave Matthews Band. Meanwhile, #2 Paramore are locked in a tight battle with #10 Ke$ha, who's been hitting the Twitter-sphere hard in an attempt to close the gap. Both #5 Linkin Park and #6 30 Seconds to Mars hold sizeable leads over their second-round opponents too, which means that, if things hold, we're gonna get a pair of Sweet 16 barn-burners: Evanescence vs. Linkin Park and Paramore vs. 30 STM. Things are about to get heated down South.

Is your beloved band on the ropes? There's still time to help them advance! Voting in all second-round MMM matchups closes Sunday at midnight ET, at which point, we'll move on the Sweet 16. Get cracking, folks!
