• This disco-inspired pop anthem finds Kylie Minogue looking for love.
  
  We're a million miles apart in a thousand ways
  Baby, you can light up the dark like a solar scape
  And I can almost feel you coming and your heartbeat race
  Someone, somebody, something, in the choice we make
  
  That elusive source of love may not currently be in Kylie's orbit, but she knows it's out there somewhere. She told BBC Radio 2: "This song is about all of our eternal quest for love and the searching and knowing that there's something or someone out there that you can relate to and makes you a better person."
• Kylie wrote "Say Something" in September 2019 with longtime collaborators Biff Stannard and Ash Howes, plus Jon Green, who worked on her previous album, Golden. It was recorded during Minogue's first session for Golden's follow-up before she even had a timeline or a record planned.
  
  She told Apple Music how the song spilled out of them that day: "I knew that the three of us would do something different, but I didn't know it would be this. It started as a beat, and we were all just singing into a microphone to capture everything."
• Oh, we're just, just tryin' to find ourselves in the storms we chase
  Baby, in an endless summer, we can find our way
  
  Though a lot of the song is a stream of consciousness, here Minogue reflects on taking a risk that could change the course of her life. She explained to the BBC: "Sometimes you wonder, 'Why am I doing this? Why am I putting myself through this?' Or "'this might not be the safest road to take,' but I think it's through adversity that we find ourselves."
• Kylie Minogue sang this live for the first time on the September 17, 2020 episode of The Tonight Show Starring Jimmy Fallon. Minogue's remote pre-recorded performance was shot on a 1980s era BBC News television camera as she sang against a VHS-style intergalactic green screen.
• Director Sophie Muller filmed the video at the Black Island Studios in London. The clip features Minogue and a dancer, Kaner Flex, moving around in front of a galactic backdrop. The singer also rides a golden horse sculpture traveling through the universe.
• Kylie Minogue released "Say Something" as the lead single from Disco on July 23, 2020.
• When Disco debuted on top of the UK albums chart, Kylie became the first female artist to score a #1 UK album in five consecutive decades: the '80s, '90s, '00s, '10s and '20s.
