Well, that's kinda what the album concept is. If she keeps it up for MM2, then I'll be worried.
I heard she was telling people at some of her shows that she wants to just go as Cry Baby for the next project, rather than calling herself Melanie Martinez.
"Soap" is really the only viable single she has in terms of potential mainstream success. Mainly because it's the only song on the album that doesn't rely on the "child/babydoll" concept.
