Most of her critique is directed at record companies, U.S. media and "longstanding racist narratives" about consumption, she said.
While the genre isn't above criticism, hip-hop "must be critiqued in a way that contextualizes it within a larger system of race and power," she added. "To do so without this context reinforces racist narratives which feed into a larger system of racism that consistently dehumanizes people of color, and serve to uphold and excuse much larger oppressive systems."
A spokesman for Universal Music New Zealand, Lorde's label, said the singer had no comment in response to the criticism.
In an interview with NPR, Lorde described how the song was inspired by the messages conveyed by the pop music she had grown up with.
"I was just sort of reeling off some of the things which are commonly mentioned in hip-hop and the Top 40," she said. "I've always loved hip-hop, but as a fan of hip-hop, I've always had to kind of suspend disbelief because, obviously, I don't have a Bentley. There's a distance between that and the life I have with my friends going to parties and getting public transport and doing the things that every other teenager does."
The lyrics in question are:
But every song's like gold teeth, Grey Goose, tripping in the bathroom,
Blood stains, ball gowns, trashing the hotel room,
We don't care, we're driving Cadillacs in our dreams.
But everybody's like Cristal, Maybach, diamonds on your time piece,
Jet planes, islands, tigers on a gold leash.
We don't care, we aren't caught up in your love affair.
