INFP based on her music, seems too idiosyncratic too be an ISFP and her music is all about Fi rather than Fe. Plus she's got that natural eccentricity I see in many INFPs; moreover, she never tries to contain it.
I don't think she's an extrovert just because she talks a lot there, I think she just does that because she's all about wanting to connect on a genuine level with person she's talking to even if its just some interviewer. Notice how she never really tries to make sense, rather she just describes what she feels, how she sees reality as functioning gets mixed up with how she wants it to. She also says "I think that..." a lot never really saying "this is how it is and that's that", she never really wants to get stuck into one perspective; she's definitely an Ne user. Like when she describes her views on religion. She also seems highly empathic.
She even says "it's changing all the time, it's like an interactive game.. you know" about how she feels on humanity.
But she does state rather strongly that she believes in "the freedom of mind" that one shouldn't be enslaved by society or ones insecurities.
Could be ENFP, but she really seems to be extremely concerned with being her own person. Valuing autonomy in a way that's typical for INxP's. I get the impression that what she's saying comes from her own mind, that she's really spent a lot of time thinking about stuff rather than having picked up and pieced stuff together like an ENFP is more inclined to. Hencewhy she's kinda clumsy and not very precise in her descriptions. There's nothing standardized about what she says.
many people fake that kind of open mindedness. many many many. i think this one is true to it.
