I don't know anything about her, only her music, but from her lyrics and playfulness she strikes me as ESFP all the way, in the same style as my ESFP sister. Hmmm. Maybe I'll have to read up about her.
Edit: I'm still going to stick with my ESFP performer typing. My ESFP sister is in vocal/piano performance in university, knows some typology herself, and says that this is the prototype of her and her classmates. Note how the interview references she "doesn't always know the meaning" herself, i.e. that is xSxP playing with language rather than xNFx focus on meaning.

Interesting. I thought she was a clear INFP. ISFP maybe, but there are a few reasons I would argue with that.
To me, she seems pretty introverted, but a rather liberated introvert at that. You can see her softness and timidity.
Remember, intuition means a focus on possibilities, whereas sensing means taking what is and perhaps molding it into something else. In her songs I can the clear use of intuition, and she does have a lot of intuition going on.
Clearly feeling over thinking, and perceiving over judging.
Yes, she does say 'lots of random stuff, no meaning', but I think she is very shy and probably didn't know how to answer the question, and really the only meaning that could be taken from the songs would be in hearing the songs themselves.
I honestly think she is too 'dreamy' to be ISFP, INFPs are otherwordly, whereas ISFP are more realists.
