Unfortunately, band breakups are nothing new and though many will surely hold out hope for a reunion à la blink-182 or New Kids on the Block, they are few and far between.

In memory of MCR, let's take a look back at five other groups that broke up, but that we wish wouldn't have.

Acceptance

Alt-rock band Acceptance had everything going for it. They were touring nationally with the likes of Anberlin and Seether and performing at huge music festivals like the Vans Warped Tour. And they received pretty decent reviews on their debut album "Phantoms" (2005).

Unfortunately, this would be all that Acceptance would do before calling it quits in 2006. 

The band was in the process of writing and demoing songs for a second album when guitarist Christian McAlhaney broke the sad news to their fans: "You see, there comes a time in a band member’s life where he must choose between the abnormal life of a gypsy rock musician and the normal life of the common man. Jason [Vena], our beloved lead singer, has chosen the latter and decided to take on the yoke of the common man. HOWEVER, the rest of us do not share in this desire for normalcy and have decided to continue in our pursuit of rock stardom."

Post-breakup, all of the members are still involved in the music industry in some fashion. Even so, these guys had a lot of potential and there's probably a lot of people out there that wish Acceptance had lasted longer than 2 EPs and an album.

Or, at the very least, that they could've released their second album.

The original Guns N' Roses

Unfortunately, the original members of Guns N' Roses began splitting as early as 1991 for various (drug-related) reasons. 

What really did it, though, was Slash leaving GN'R in 1996 over arguments on where the band was going musically, because that event led to Matt Sorum and Duff McKagan's departure from the band as well, leaving Axl Rose as the only original and consistent figure throughout GNR's career.

Excluding Rose, the band has seen 21 different members over the course of 28 years… although Evanescence is really giving GN'R a run for its money in terms of how often its lineup changes (minus vocalist Amy Lee, the band has had 11 different members over 18 years).

Everyone held out hope for a reunion between the original members of GN'R at last year's Rock and Roll Hall of Fame induction ceremony, but, alas, Hurricane Axl Rose 2.0 came around and squashed that idea.

Well, that and the fact that no one seemed to know whether Izzy Stradlin would even show up or not.

And while "Chinese Democracy" (2008) got mixed to positive reviews from critics, everyone has to admit this current version of GN'R isn't nearly as awesome as the one that gave us "Welcome to the Jungle" and "Sweet Child O' Mine."

The Civil Wars

Like Acceptance, singer-songwriter duo The Civil Wars had only released 2 EPs and an album when they suddenly went on hiatus last November.

Everyone thought they would have a long and prosperous career ahead of them—they were nominated for tons of awards and had even won 3 Grammys! 

And then… Bam! The Civil Wars started canceling tour dates and then left a message on their Facebook and Twitter about "internal discord and irreconcilable differences of ambition." 

Wait… What?

Many speculated that band mates Joy Williams and John Paul White were romantically involved with each other, even though they were both married. However, we'd like to think that there are such things as happy marriages and that this split happened for other reasons.

Luckily, there's still hope for The Civil Wars and its fans as Williams tweeted that she had been in the studio "listening to some new @thecivilwars songs" only a month after going on hiatus!

'N Sync

One of the biggest American boy bands of the 90s and early 2000s, 'N Sync only released 3 albums before announcing a "temporary hiatus" in 2002.

(It's always a "hiatus" with those darn musicians!)

All 5 members of the group are still in the entertainment industry to varying degrees and there's apparently still hope for a reunion.

According to Lance Bass, "We've always discussed it. It's always a possibility and we still owe some records to the record companies." But that announcement was in 2008 and it's now 2013—Justin Timberlake's got a new album and tour and JC Chasez has been busy serenading sororities.

Unfortunately, it doesn't look like a reunion will be coming any time soon, especially due to JT's busy schedule, but at least they're all still friends and considering the idea, right?

Let's just hope that this reunion—if it ever happens—comes sooner rather later, because who would want to see a group of 50-year old guys trying to act like they're still teenagers?

Swedish House Mafia

In what may have been the biggest news last year for EDM fans, Swedish House Mafia announced that they would split after going on tour (aptly named "One Last Tour") and performing at the 2013 Ultra Music Festival, which was just 2 days ago!

As with Acceptance and The Civil Wars, SHM's career seemed way too short. Having only been formed in 2008, the EDM supergroup was already being nominated at the Grammys for Best Dance Recording in 2012 and 2013 (though SHM lost both to Skrillex).

Although Sebastian Ingrosso, Axwell, and Steve Angello are all talented DJs and producers in their own right, music fans will surely miss their collaborations together to make fun and memorable tracks like "Save the World" and "Don't You Worry Child."

Even if they don't come together under the name Swedish House Mafia ever again, one can only hope that these 3 talented guys will continue to work with each other on future projects.
