A little while ago, I saw someone online talk about what makes "The Catcher in the Rye" so enduring. The comment was something to the effect that it perfectly captures the attitude of being a teenager: cocksure and savvy interspersed with moments of doubt that reveal a deep uncertainty. I wish I could find the original comment, because it was much more eloquent than I'm being.
In any case, Lorde's debut album got a lot of attention for her 'anti-pop star' approach to the genre. Her songs are a direct contrast to most pop, especially "Royals", which is all about not living the life seen in music videos. Her whole album really paints a picture of a time and place, and I suspect most of us could relate to something adolescent in her lyrics.
Musically, the album is also great. If you like languid, minimalist pop songs with excellent harmonies, you'd like this album. "Buzzcut Season" is a standout for me, probably because of the simple harmony on the pre-chorus and chorus.
