Beyoncé surprised fans with an unplugged performance of her new song, "Die With You," on TIDAL Saturday (April 4).

Dressed comfortably in a black T-shirt and baseball cap, she plays the piano as she sings the bluesy R&B ballad. "'Cause darling I wake up just to sleep with you / I open my eyes so I can see with you / And I live so I can die with you," she sings emotionally on the chorus.

Putting her all into this heartfelt tune, it makes you wonder who's the one behind the camera. And after the performance, Beyoncé jumps up, looking very proud of what she just played. Then the camera turns around and reveals that Bey's husband, Jay Z, was the cameraman all along.

What makes this song even sweeter is the fact that Saturday marked the couple's seventh wedding anniversary. Bey and Jay wed in a very private but lavish ceremony on April 4, 2008, in New York City.

And if you've recently joined TIDAL, then you probably got to see the full performance on the music streaming service. However if you're not, you can see the full video below (via PerezHilton) and watch a clip that Beyoncé posted on Instagram above.

Beyoncé's new video is just another way TIDAL is making good on its mission to "offer something different." But Beyoncé and Jay aren't the only ones; the White Stripes, Daft Punk and Alicia Keys also dropped new material on TIDAL this week.
