Miley Cyrus has a tendency to come in like...like, some sort of monstrously large steel ball of some kind. I wish there was a term for it! Oh, well.

Anyway, she's just done it again...even if, erm, it doesn't seem like she meant to this time.

"Nightmare" is a newly surfaced jam from the Bangerz beauty, which arrived out of nowhere on the Internet this afternoon. There's no word on who or what it's from, exactly: a post-Bangerz era offering is a possibility of course, although the song doesn't quite seem as "weird" as she's suggesting her music might sound as of late.

The song has all the makings of a Dr. Luke production, from the opening guitar strum that recalls Kelly Clarkson's "Since U Been Gone" to those searing synths, which carry a touch of the glossy synth-rock of Kesha's Warrior. There are elements of Nicki Minaj's "The Night Is Still Young" in the chorus and bridge, too — also a Luke production. That's only a guess, though!

Most importantly, the tune is huge. Really massive.

"Nightmare" veers far away from Miley's foray into hip-hop territory on Bangerz, instead wandering back into the electro-pop-rock territory that made 2010's Can't Be Tamed such an incredible record, still. "I woke up in another life where nothing's really dangerous and everything is black and white, and no one even knows / I woke up in a broken dream with no one lying next to me / It's not how it's supposed to be, so why'd you have to go?" she belts out on the urgent pre-chorus — which recalls the build-up of Bruno Mars' "Locked Out Of Heaven" — just before the synths come blaring in for a stadium-sized wailer of a chorus.

She sounds fantastic throughout the heart-wrenching break-up anthem, which certainly doesn't make the wait for Miss Mileybird's post-Bangerz opus any easier. Every individual "He-ay!" and handclap is a pop triumph.

Thank the Pop Gods for this entirely unexpected Miley #blessing.
