• This tune finds Katy singing about that moment after a night spent clubbing when the music's over but you're helplessly overpowered by the voice in your head telling you to keep going:
  
  "I need somebody to calm me down
  A little loving like Valium
  I need somebody to knock me out."
  
  Katy told Q magazine "The song is about going home, realizing you are a bit lonely and there is no one better to spend your time with. It's been quite a while since I had a cuddle."
• Katy described the song's infectious house beat as "uncomfortable, something I like but I shouldn't."
• The song was produced by London-based producer Geeneus, who worked with Katy on much of her 2011 debut On a Mission. This was one of seven tracks he manned the boards for Little Red. "There are quite a few [Geeneus] tracks on the album… He's definitely a massive part of it," Katy noted to Billboard magazine. "He's kind of like my Timbaland to Missy Elliott."
