Bow down to Beyonce!

The Queen Bey dropped 'Bow Down / I Been On' on her website, and from the sounds of it, the once-retired Sasha Fierce is back in full swing.

"I know when you were little girls / You dreamt of being in my world," Bey sings. She alludes to her brief hiatus, as well as her strong-as-ever marriage to Jay-Z -- which, obviously, inspired her album title: "I took some time to live my life / But don't think I'm just his little wife / Don't get it twisted / Bow down b----es, this is my s--- ... I'm so crowned / Bow down, b----es!"

After a brief breakdown and melodic runs, the 'I Been On' half begins. It opens with a deep-dubbed rap "I been on / Who gon' take me off?" over Bey's hypnotic harmonies.

Even the cover art shows how long Beyonce has been running the game -- she's a kid surrounded by trophies, medals and ribbons, and you know that she earned them all.

The song doesn't appear in the leaked tracklisting that was posted about two weeks ago, but there's a chance it's a B-side or an interlude. The 'Bow Down' half, if extended into a full song, would likely have a shot at being released as a single, but both together is likely just a teaser for what to expect from 'Mrs. Carter.'

You heard the lady. Bow down. All hail the King Bey!
