• This acoustic country-tinged ballad finds Kesha reflecting on her resentment towards a lover who has done her wrong.
  
  I don't hate you babe
  It's worse than that
  'Cause you hurt me and I don't react
  I've been building this thing up for months
  
  Kesha is holding onto her negativity that was created by the unspoken trauma. The singer said: "Resentment is such a powerful and destructive emotion and in my experience is more complex than hate or anger."
• Kesha is joined on the track by the LA-based songwriter Wrabel, Beach Boys legend Brian Wilson, and country singer-songwriter Sturgill Simpson.
• "Resentment" was originally written by Wrabel, Madi Diaz, and Jamie Floyd, with later co-writing from Kesha. It was produced by John Hill. The song originated during a highly productive Nashville writing session in early 2018. Diaz, Wrabel, and Jamie Floyd wrote both "Resentment" and Madi Diaz's later single, "Crying in Public," in a single day while working in the basement of Creative Nation on Nashville's Writers Row.
• The song's grainy visual is an intimate self-shot video recorded by Kesha on her iPhone 11 Pro.
• Q Magazine asked Kesha how she persuaded Brian Wilson to come on board for this song. She replied: "Pet Sounds changed my life, so he was always top of my list of people I would love to collaborate with, but I never thought in a million years he would (a) know who I am or (b) take the time to collaborate. But if you don't ask you'll never know, so I threw it out there in the universe. When I heard his vocals I just broke down crying because I never thought it would actually come to fruition."
• Wrabel, who is a close friend of Kesha, shared the song with her informally. After Kesha decided she wanted to record it, Diaz worried how the emotionally heavy track would translate into the pop singer's catalog.
  
  "Wrabel sent her 'Resentment' just as a friend," Diaz explained to Billboard. "Kesha was like, 'Oh my god, I want to cut it.' And I was like, 'We're gonna ruin a pop star's career.' But she killed it. She had Sturgill sing and Wilson sing on it. And, you know, the song came and went and Kesha is thriving. Nothing horrible happened."
