Some fans think that since she's had conceptual albums before, that she should stick to that..they will use 20 Y.O. and Discipline as examples--moreso because she didn't write as much on those albums.
Honestly, she's better when she really has something to say..but I wouldn't mind a more free, happy-go-lucky Janet a la A4U..even MFN was energetic, colorful, and playful..but had a message.
