Judging from the LQ version/snippet (it was only 2 minutes long), the song is basically the same, except you can really tell it's Miley singing the female vocals. It might have just been the awful audio, but I thought it sounded like they added a dubstep breakdown as well.

Where the Miley stans at
It's not like she gives us much to talk about.
My avi is so cute. The entire Wonderworld tour was magical.
Not that I'd know personally, considering she's never came here on tour.
Like, what kind of slay? Pop girls twice her age wish they could put on such a show. The energy, the stamina, the serving of vocals from 2:49+? Who else is flying over a sea of people though? And the end choreography? I've had enough.
According to Ken Baker from E! News, we should be getting some, "Fun, non-studio songs" within weeks. but "no album yet". maybe he's talking about the acoustic videos she did???

At least I hope so.
