Woo

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."
