Christina Aguilera's probably quite fond of The Voice's IV drip of career juice, considering her drought of a year before it. In what's starting to look like a quest to record with every coach on the show, she and Adam Levine are set to perform a new track on next week's show, then drop the studio version last night.

The collaboration's called "Moves Like Jagger," which all but guarantees there's going to be some "swagger" in the lyrics. As far as the sound, we won't know until either next week, when it officially lands on iTunes, or until the Internet washes a leaked version ashore. It'll be "upbeat," which in news-wire terms could mean anything. So let's turn to fan ChristinaVIP, who's evidently heard this. Quoth:

"Its a great song, sexy, fast, and would be very radio friendly. It's more Maroon 5 featuring Christina. She sounds great and doesn't over sing in it. Not sure what it's for but if I had to guess I would say Maroon 5's next album."

Sound good? Not good? Better than "Nasty," Xtina's duet with Cee Lo Green, or at least Maroon 5's "Give A Little More"? You tell us.
