Singer Lorde: ISFP or INFJ?

I've heard strong arguments for both sides. On the one hand, she displays strong Fi and Se in her songs because they focus so much on her emotions + the present...but on the other hand, she also has very strong Ni in her songs. In fact, if you pay close attention to her lyrics, her Se isn't at all like the Se of an XSFP personality type. She uses heavy symbolism (Ni) in her music and almost appears to be mocking Se, like an immature INXJ. Also, in her interviews she seems to focus more on the impact her music has on other people, and her songs like "Team" sound more collectivist (Fe) than individualistic (Fi).
