A day before the official release of Britney's new single, Work Bitch, the song has leaked online. And as expected, it's a massive club banger! This song is amazing. Written by Will.I.Am and Sebastian Ingorsso protégé DJ Otto Jettman, Britney give fans the secret to her success: " You want a hot body? You want a Bugatti? You want a Maserati? You better work bitch!" she coos in the song's opening lines. The song recalls the attitude of ‘Blackout’, but in a song crafted for a post-EDM pop landscape. This record wouldn’t sound like it does if EDM hadn’t happened, but at the same time it’s a Britney track first and foremost. The most exciting bit is the middle eight which goes all epic and spacey with some proper hands-in-the-lasers lyrics says popjustice.com. The first few seconds is a thumping beat followed by an addictive club sound that sets the mood for the rest of the song. "Work Bitch" follows the June release of "Ooh La La," the lead single to "The Smurfs 2" soundtrack. Earlier this year, Spears scored another Top 5 hit with her Will.i.am collaboration "Scream & Shout."
