^ I hope she gets depressed again.
(Kidding)
Sad Olivia= The Lost Lolli/ Mini-Album era
Happy Olivia= The Cloudy Dreamer T_T
The Cloudy Dreamer I guess doesn't count though. She said in interviews she'd be making more radio friendly music after NANA for a short period of time since fans from her NANA music would be like wtf to her Lost Lolli type stuff. I can't even speculate what she's gonna do next. Her sound isn't very consistent, which I like about her.
