First the Imagine Dragons at the Grammys, now Tame Impala on the "Divergent" soundtrack -- Kendrick Lamar is all about the out-there collaborations lately. The latter dropped on the Web Friday (March 7), and if you were expecting something as mind-blowing as K-Dot jumping in on "Radioactive," you won't be disappointed.

"Backwards" is a new take on Tame Impala's "Feels Like We Only Go Backwards," off of their 2012 record Lonerism. A more jagged spin on the smooth jam, the ethereal chorus, ("Feels like we only go backwards") lilts in the background, overlaid by Kendrick's lightning fast rhymes: "No rules/ now feel the energy we go through/ I told you/ Put my fists like I'm supposed to/ I showed you."

The pairing might seem unexpected but, according to music supervisor Randall Poster, that's the point. The merging of the two sounds is meant to represent the collision of past and future in the "Divergent" universe — a world in decay.

"I think that one of the challenges for a movie like this is that it's set in the future and so you sort of have to figure out, 'OK, what might music in the future sound like?'" Poster told MTV News. "The film is actually set not in a perfected future, but actually kind of in a future world that is deteriorating. And so we wanted to create a musical element that had reflected on current music sounds, but also felt kind of time-forward and had a certain futuristic element."

Poster said he was particularly inspired by Kanye West's Yeezus when ...

Depending on which news feed you subscribe to, the current crisis in the Ukraine could either bring the U.S. and Russia to the brink of another Cold War, or just be the latest muscle-flexing from frequently shirtless, macho Russian president Vladimir Putin.

The reality, though, is that the clashes between pro-Western activists and troops loyal to now-ousted president Viktor Yanukovych have taken 100 lives since government protestors peacefully occupied Independence Square in Kiev in November. And now, secession talk from the southern Ukrainian region in Crimea has brought tension between American and Russia to a dangerous boil.

As the back-and-forth continues, MTV News takes a look at how we got to this point:

How It Started
Anti-government protesters occupied Independence Square (known as Maidan) in November after president Yanukovych backtracked on a financial deal that would have brought Ukraine closer to integration into the democratic European Union. Instead, Yanukovych chose to ditch the EU deal in favor of closer ties to former motherland Russia.

In early December, more than 800,000 people demonstrated against the moves, marking the biggest such protests since 2004-2005 Orange Revolution that helped bring a pro-Western regime to power.

Yanukovych put new anti-protest laws in place and his police force attacked the peaceful protesters, killing at least 100 and injuring more than 600 during 48 hours of clashes from February 18-20. Opposition activists were also abducted and beaten in an effort to end the protests.

Why Choose Russia?
In addition to being a huge market for Ukraine's exports and supplier of much of its natural gas, Russia promised the cash-strapped nation a badly ...

It's a story of two crime-fighting partners, one of whom might, after years of service, become consumed by the darkness.

Sound familiar? That's the basic premise of But it also is a handy synopsis of the relationship between Obi-Wan Kenobi and Darth Vader in the saga.

Once we realized that, it only made sense to wonder what "True Detective" might look like if it took place in a galaxy far, far away. Thanks to this mash-up that puts "Star Wars" characters in the "True Detective" main title sequence, we never have to wonder again.

Anakin Skywalker and Obi-Wan Kenobi take the place of Matthew McConaughey and Woody Harrelson as both their younger and older selves, with appearances by Anakin's tortured wife (Padme) and his daughter (Princess Leia), who is quite literally a rebellious teenager.

But who, in this version, is the yellow king? C-3P0 probably wouldn't be a bad guess.

Check out the mash-up, and hope HBO gives us a second season of "True Detective" that can match this level of awesomeness.

Ed Sheeran's not pulling any punches on the first single from his new album, except when it comes to the radio edit.

After all, the song (Ed wouldn't reveal the title just yet) does feature several rather fantastic uses of the F-word, a fact that probably won't go unnoticed by programmers at radio stations around the world. So, for the first — and perhaps only — time in his career, he was willing to compromise.

"I tried other words, I tried 'mess,' I tried 'funk,' lots of other things, but none of them worked," he laughed. "I think if you're going to swear on a track, make it worth it. There's no point swearing just for the sake of it ... but, if taking away a certain cuss word lightens the load of a song, I don't agree with that. So, I've kept certain words in just because it makes the song what it is. But I'm I'm definitely giving radio and edit they can play, because I'd be mental not to."

Of course, as his fans know, F-bombs are nothing new for Sheeran ... but it's the way they're used in this new song — with a pissed-off purpose — that may come as a surprise. And, yes, even Ed will admit that the single will definitely raise a few eyebrows. That's practically the point.

"When I wrote the first single, the album was pretty much done, and I was just going into the studio to vent; something frustrating had happened and I just wanted to get it all out," ...

Sin City is the place you go with your eyes open, or you don't come out at all.

Much the same can be said for the new , too. The consequences aren't as dire as, say, losing your life, if you happen to miss a face or two in the new trailer. Still, with so many blink-and-you'll-miss-it moments in this first glimpse of Robert Rodriguez and Frank Miller's return to "Sin City," it's worth stopping down to take a closer look.

Here's an eye-opening guided view of the various faces populating the new "Sin City" trailer.

Let's start with an easy one: That's Ray Liotta! You know him from such films as "Goodfellas" and "Killing Them Softly." Here, he's Joey, a bad businessman looking for a way out of a bad marriage. Apparently, that way includes a silenced pistol. But who's that up there in the skylight?

That's Josh Brolin! He plays crusading photographer Dwight McCarthy. But didn't Clive Owen play Dwight in the original? He sure did. So what's Brolin doing here?

Let's just say it might be a temporary stay and leave it at that. As for why Brolin looks so messed up, you can blame that on...

...Eva Green as Ava Lord, the titular dame to kill for. She's an old love from Dwight's past, and she resurfaces to ask for his help in getting out of her troubled marriage.

But it doesn't really look like Ava needs Dwight's help, does it? It shouldn't spoil much to tell you that Ava is going ...

There's only one thing that's certain about Kanye West: the man is totally unpredictable. His surprise performance with Rick Ross and Big Sean last night was impressive to say the least. Speaking of impressive, Miley Cyrus and Katy Perry gave quite a show on Twitter yesterday, resulting in some rough words and one violent threat. Those, plus Kesha's post-rehab plans and some suggestions for weekend watches are Friday's top stories.

Kanye West & Big Sean Join Rick Ross For "Sanctified" Performance
The Arsenio Hall Show has never seen such a surprise. On Thursday night's show, Rick Ross' "special guests" turned out to be none other than G.O.O.D. Music hit makers Big Sean and Kanye West.

Miley Gives Katy A Tongue Lashing, Katy Responds With A Spanking
After Perry appeared on an Aussie morning show and made some snarky comments about the kiss the two singers shared at one of Cyrus' Bangerz Tour shows, the "Adore You" singer responded with some snark of her own, targeting Perry's ex-boyfriend John Mayer. "Girl if ur worried abt where tongues have been good thing ur ex boo is ur EX BOO cause we ALL know where THAT [tongue] been."

The tweet had everyone on the edge of their seat. Was this the end to one of our favorite duos? Perry put it to rest when she tweeted back, "Oooo gurrrl I'm gonna give you the BIGGEST spanking when I see ...

Batkid, the superhero phenomenon better known in his daily life as five-year-old cancer survivor Miles Scott, was set to turn the Oscars stage into his very own Gotham City — but on the evening of the Academy Awards, those plans changed.

Instead, "Captain America" actor Chris Evans was called onstage to present a series of movie clips meant to honor superheroes. Originally, "Spider-Man" star Andrew Garfield was supposed to present the clips, ending the segment by bringing Batkid on stage and honoring him as an official superhero.

Rumors began circulating that it was Garfield's decision to withdraw from the segment, with Page Six reporting that "in the middle of the dress rehearsal, Garfield decided he didn't like his lines." The report further states that Garfield rewrote the script, and when it was deemed "not appropriate" by producers, "Garfield had a tantrum. He stormed off. Miles and his family, who were at the rehearsal, were devastated."

Now, Garfield's own representatives have spoken out about the supposed snub, to dispute those claims and make it known that Batkid and Spider-Man are very much on speaking terms.

"Here are the facts," Garfield's rep Rupert Fowler told Us Weekly. "In full collaboration with the Academy and the show writer, Andrew prepared a segment for the Oscars to honor Miles Scott as the true hero that he is. At some point overnight on Saturday/Sunday morning, it was decided by those running the show that the segment didn't work in the ceremony."

"They decided to pull it - Andrew and Miles were equally upset," ...
