I think it would have fit in pretty well. Like, a lot of it, well at least part, is about his reaction to the record leaking (I think)..."I finally broke on Christmas Eve / In an Outback Steakhouse bathroom / While my family ordered for me." Pretty sure that's about the leak of the record cause that happened on Christmas Eve and he told me a similar story the first time I interviewed him. And the rest is lyrics just like the rest of The Upsides.
I don't know, I think it fits in with the realist pop punk theme perfectly.
