Songfacts®:

• "Fast" is a return to Demi Lovato's electro-pop roots following the rock-infused sound of her previous album, Holy Fvck. The track is about the exhilaration of new love and burning desire. Lovato bristles with feelings of impatience and craving, looking to skip the slow burn and dive headfirst into intimacy.
• While Lovato hasn't explicitly confirmed the song is about her marriage, it's hard not to connect the dots. On May 25, 2025, she tied the knot with Canadian musician Jordan "Jutes" Lutes at the Bellosguardo Estate in Santa Barbara, California.
  
  "I tend to write from the place I'm in at the moment," she told People. "Lately, it's been amazing, I've been writing nothing but love songs and sexy songs because I'm in a really good place."
• Released on August 1, 2025, Lovato teased the house-driven, high-energy track on social media ahead of its release, posting: "My pop music coming back to life after we had a funeral for it."
  
  And yes, she really did hold a "funeral" for her pop sound, posting a photo of herself and her team dressed in black, with Demi defiantly flipping the bird to the camera under the caption, "A funeral for my pop music."
• Demi Lovato co-wrote "Fast" with:
  
  Los Angeles songwriter Chloe Angelides, a longtime collaborator with Demi. Their previous collaborations include "You Don't Do It For Me" and "Still Have Me."

  Maryland native Kevin "Zhone" Hickey, who has worked with the likes of Troye Sivan ("Rush") and Kesha ("Joyride"). Zhone also produced the track.
• The music video, filmed by British photographer and creative director Daniel Sachon, takes us on a wild ride through a surreal, chaotic cityscape. Along the way, Lovato passes by TV screens projecting internet memes that had featured her, including the Poot Lovato meme.
  
  The video culminates in a pulsating nightclub scene, perfectly matching the song's energetic and fearless spirit.
  
  Sachon is no stranger to high-profile projects, having worked with high-profile clients such as Kim Kardashian for Skims, Dolce & Gabbana, and top models like Candace Swanepoel and Daphne Groeneveld.
