Songfacts®:

• "Love/Hate Letter to Alcohol" is a song dedicated to Post Malone's struggles with booze. He admits there are many detrimental side effects to extensive alcoholic consumption, such as getting into drunken fights. He references how after one brawl, he got punched in the mouth hard enough for some teeth to fall out.
  
  I was laid out flat, like a centerfold
  Jakey and his partner drove me home
  Lookin' in a mirror, somethin's wrong
  Let me get my dentist on the phone
  
  However, Malone goes on to say he's not willing to give up alcohol because it's "the only way to drown my sadness."
• Malone wrote "Love/Hate Letter to Alcohol" with his go-to collaborator Louis Bell and his pal Robin Pecknold of Fleet Foxes. Malone has long been a fan of Fleet Foxes, tweeting in 2015 they are "the only group that I love every single song of."
• Malone first hit Pecknold up on Instagram and they started talking on social media. Pecknold invited Malone to be a part of Fleet Foxes' 2020 Shore album, but time constraints prevented it happening. Eventually, Malone invited Pecknold to jam some rock and roll. During their session, the Fleet Foxes mainman played the "Hollywood's Bleeding" singer an idea he was working on. Malone loved it, so Pecknold gave the track to him. That idea became "Love/Hate Letter to Alcohol."
• Malone's admiration for Pecknold is mutual. "He'll text me every once in a while and it's always a really fun thing to receive," Pecknold told Audacy of Malone in 2020. "To have that pop up in my iMessages, it always feels like a glitch in the Matrix or something."
  
  "He's a super sweet guy, he's a real gentleman, and he's probably the best melody writer in the business right now. I think," Pecknold added, "and by some glitch in the Matrix, we have a casual friendship."
• This song's subject of a love/hate relationship with alcohol fits the theme of Post Malone's fourth album, Twelve Carat Toothache. "It's the bipolar aspect and the duality of everything," he told Apple Music's Zane Lowe. "And so, there's a lot of things very much on this record that are tongue in cheek. And I think this whole record is the most honest record I've made."
• Post Malone performed "Love/Hate Letter to Alcohol" on the May 14, 2022 episode of Saturday Night Live. He crooned the track while surrounded by a backing vocal group that included Robin Pecknold.
• When the song debuted at #70 on the Hot 100 dated June 18, 2022, it gave Fleet Foxes, who formed in 2006, their first hit on the chart.
