It's all about getting her name out there at this point. Maybe they realized the "Rihanna-strategy" (even if wasn't planned) was genius:
1. Release two quick albums somewhat reminiscent of the current it-girl
2. Explode with your third album GGGB: Ritaoded is coming
She never said her second album is ready...
She just said she put the songs, that didn't made it onto Ora, but need to be heard by the public, in a folder for album number two.
