Right Now will be the second single. She actually wants a hit to keep her momentum going (like the Loud era). That's why we haven't gotten the second single yet.
Wait, where's that news coming from? 'Cause I just saw "Nobody's Business" being named the second single...
But seriously I dunno. Nobody's Business sounds good on the radio (heard it the day after Unapologetic leaked on the radio ) but I'm not sure if that'd be a good second single.
