• Here, Tove Lo sings about the heady emotion of a night out among friends fueled by alcohol and recreational drugs:
  
  You know I'm under the influence
  So don't trust every word I say, I say
  When I'm under the influence
  It's a blur, but I want my way, my way
  
  She explained to Genius: " I have a lot of nights where I'm in just the best high. I love everyone around me. I've gone pretty far in experiencing that love for people—just saying all this stuff, and you kind of have to own up to that the next day and take it back. But that's what I'm owning up to in the chorus.
  
  But I'm also saying a little bit of, 'You know, maybe you don't believe me after looking into my eyes, after a night like that.' Just being honest about not being honest: I think there's something really fun and beautiful in that. Bunch of people stroking at each other just feeling the love. It's fun."
• This was the first song Tove Lo wrote following vocal chord surgery at the beginning of 2015. She said:
  
  "I wrote 'Influence' after my vocal chord surgery, which was in January last year. As a singer, I don't think I realize how much I need this until that happened to me. It was after two months of going out of my mind at home, 'cause you can barely speak. You can't be in loud environments. So basically, I was locked in my apartment for a few months. But once I got back out and I could sing again, it was the most amazing feeling, and my voice was so light and bright. I could hit any note. It was amazing, but I didn't really have that much control of it."
• Wiz Khalifa steps in for the third verse, rapping about meeting a single-minded girl at a club. The Pittsburgh MC recorded his part in the studio with Tove, and the pair ended up smoking out of a bong they made from an apple. "I told him, 'I know how to do it too,'" she told Billboard magazine laughing at the memory. "He didn't trust me."
• Tove Lo recalled Khalifa's contribution:
  
  "He's like me - he has his pen and paper, writing. I was like, "Whatever you're feeling - I don't want to like 'Well what are you really saying there?'" I wanted him to do his take on it."
  
  I think it adds that last piece of energy that it really needs," she added. "I also love that he sings part of the last chorus, like some harmonies. He just nailed it. I think it was great."
