• This song finds Rihanna's ex struggling to get over their relationship. The Bajan songstress is missing him too and tells him to "send for her."
• Travis Scott was Rihanna's rumoured boyfriend at the time of the release of Anti. His sole contribution to the album is chanting on this song: "Wooooo, Woooo, yeah."
• It took eight people to write this track, namely Jean Baptiste, Kuk Harrell, Hit-Boy, Travis Scott, D. Rachel, The-Dream, The Weeknd and Rihanna.
  
  The-Dream is a longtime Rihanna collaborator, dating back to her 2007 smash hit "Umbrella." He told Billboard magazine:
  
  "When I first heard it, there was just mumbling on it. And Rihanna wanted me to come in and make sense lyrically, just come in and write the record. Travis' part was there already. That's what I did."
• The writers penned "Woo" in a studio house Rihanna hired in Malibu. "She had a lot of dope writers and artists there," Hit-Boy recalled in a Rolling Stone podcast. "I was in a room literally with Travis Scott, the Weeknd, and Ty Dolla $ign. I made that beat from scratch in front of them and Travis started doing the 'Woo' melody, the Weeknd did his melody, and Ty Dolla $ign was doing some stuff. It was a dope moment."
