[My mindset in creating the song was] Dark and heavy. That whole album is depressing. [chuckles] It’s 10 songs. I had 4 written for a while, and had to write 6 or 7 others. “Just One Thing” was one of the last ones. There was just a 2-week period where I was just writing for 12 hours a day every day, trying to come up with new stuff. Really locked into a heavy, emotional mindset. Isolated pretty much, in my basement for way too many hours a day. You kind of start to go crazy. That comes through. The high hats in that song are anxiety-producing. I also just wanted a fast song. I wanted a fast, dark, heavy song that was super simple. It worked, I think.

When I was writing it, I was thinking that this is the exact type of song that I want to write, in the sense that it’s musically fast, and I come from a punk background, that was always my thing. Locally there was a strong punk scene, my local heroes were all punk kids who were like a year older than me, and that’s where my love of fast music comes from, and that’s why I love a lot of trap music, because it’s fast and a lot of progressions are just two chords, right? They’re punk songs, in a sense. So musically, it’s exactly what I want. It’s the type of music that I like and I wish more people would make. So it has that going for it. It’s one of the first songs I wrote that has a very obvious chorus to it. And when I wrote the first version of “Just One Thing”, the hook wasn’t as catchy, and it kind of rambled a little bit. It was kind of convoluted. But when I was recording it with Will Yip at Studio 4, Will suggested that I cut that rambling part, and just keep the immediate, catchy part, and just repeat it. And it worked! Once I heard it recorded I understood that if one of my songs was to resonate with people who don’t like my music, this would be the one. If one of my songs had to be on the radio, for whatever reason, that would be the one.
