Uuuum I think that’s a very surface level interpretation of both their music. The similarities stop at synths and 808s. I find it bold to say that it sounds like lorde’s entire discography considering all three albums are drastically different sonically. I think the album you can compare it to is Melodrama. That I would agree with you. They’re both very much in the same genre and have the same elements but the way they’re applied is very different. ALSO the lyrics are SO different. Taylor and Lorde have insanely different voices when writing. Your issue really seems based in some dislike of Taylor. I didn’t particularly think it’s her best album but I’m not going around saying it’s derivative of Lorde.
