Alicia Keys and Kendrick Lamar showed up on The Tonight Show the other night to perform “It’s On Again,” from the The Amazing Spiderman 2 soundtrack, and they just happened to be joined by a few other folks who also contributed to said soundtrack. The legendary Johnny Marr, Hans Zimmer and AraabMuzik (tearing it up on the MPC, on which he may just be the king) all joined in the fun, and despite the song itself being mediocre at best (Lamar’s rap at the start is far and away the best part), the performance itself was still memorable. We’ll never know how Keys will feel years from now about that mullet she’s sporting, but isn’t that the beauty of the internet – everything now lasts forever.
