Ironically, she’s on record as hating being typecast as “academic”. She probably just reads a lot and it happens to inform her music, which I think is to her credit in that she isn’t referencing heady things for the sake of being perceived as smart or whatever. There’s a big difference between this versus doing the same thing for ego reasons. Not to mention her music is extremely unique and not a sterile imitation of really anything. She’s cool!
