Songfacts®:

• Sam Smith wrote this song with Eg White (Adele, Will Young). He told 4Music: "This track is me at my most vulnerable. I had no energy when writing this and this is the demo. It's me at my rawest."
• The song is a track from Smith's debut LP In The Lonely Hour. He told The Sun: "This album is about me falling in love with someone who didn't want me back, which has happened many times."
• This was one of two tracks on In the Lonely Hour that Sam Smith penned with Eg White ("I've Told You Now" was the other one). He recalled to Digital Spy: "With all the songs we did together, we wrote in a very odd way. We didn't actually start making music at the beginning of the session, we would sit and he would just ask me about what I was going through."
  
  "With this song, I showed him my text messages. I was showing him some things I had been saying between me and another guy, and he was writing down everything I was saying. He started playing some music and the song was then basically already written. 'Good Thing', for me, is the darkest song on the record. If you actually listen to my vocal, I'm not even trying to sing or sound pretty because I was so upset and sad. I kind of loved that and I feel like it really came across in the song."
