We all love Lorde's first solo single in a billion yonks, 'Green Light,' right?

'Green Light' is the song that taught us so much about bodycon dresses, Superstar trainers (we can wear them again) dancing on car roofs (we should try it) and more.

The single is the first to come from her new album, Melodrama, set to release on June 16.

Melodrama is the result of two years of writing from the 20-year-old Lorde, and will apparently explore her feelings of newfound maturity.

The 'Royals' singer explained in a Facebook post:

If I'm being real with myself, in some ways I stopped feeling like a teenager a while ago. Sometime in the last year or so, part of me crossed over. For one thing, I made a very deliberate choice to withdraw for a little while from a public life. I haven't had my hair or makeup done in a year, the free handbags dried up LONG ago, and the paparazzi at the airport are almost always for someone else. And let me tell you, as much as I love being full noise album cycle girl, it's been a motherfucking joy. (every once in a while I am recognised on the street - one of you breathlessly clutches my hand, shaking and speaking quickly, and I feel this SHOCK of love.) I turned inwards to my friends, my family, towards this moment, so I could learn more about who I was, and so I could let this new project show itself to me. And oh my god, it was a colossal year! One for the ages. I maxed out every single emotion I have in the best possible way, the colours still aching behind my eyes like this weird blissful hangover. My heart broke. I moved out of home and into the city and I made new friends and started to realize that no-one is just good or bad, that everyone is both. I started to discover in a profound, scary, blood-aching way who I was when I was alone, what I did when I did things only for myself. I was reckless and graceless and terrifying and tender. I threw sprawling parties and sat in restaurants until the early hours, learning what it's like to be an adult, even talking like one sometimes, until I caught myself. All I wanted to do was dance. I whispered into ears and let my eyes blaze on high and for the first time I felt this intimate, empire-sized inner power. And then I wrote a record about it, all of it, so much more than what I've written down here, and I'm in new york getting it done.

And you know what, has anyone noticed her whole vibe is a little more...cheery?

A little less...moody?

Farewell dark flowing curtain of curls and sorceress-dark lips.

The lob is most certainly strong in this one.

Thankfully, Lorde sat down and spoke to Vevo Offscreen about her new aesthetic. She told them that the switch was most certainly a conscious one, saying, 'I was very aware that this is the first thing that people had seen from me in three years.'

But it wasn't an arbitrary change. Much like all of her art, it was an expression of her personal life:

I was picking up where I had left off, which was, I always had dark lipstick on and a weird kind of outfit. And this time, I was like, 'I want to look the way my friends see me.' I want to feel like I could be any one of the young people who listen to my music.

She then goes on to describe the 'Green Light' song and music video, which she calls 'symbiotic'.

Again, wanting art to imitate life, she knew it should follow her on a real night, with the same shoes, dress and vibe.

Lorde also admits how difficult it is to dance on top of a car, 'Cars generally aren't not built to have a girl dancing around, losing her mind on top of them.'

Not that it will stop us having a go.
