"155" is a heavily layered synth-driven track that contains handclaps and "Cure-esque guitars." The handclaps were Barker's idea, who noticed its prevalence in hip-hop songs and wanted to incorporate into a rock song. "Lillian" features programmed drums and acoustic guitars, and was inspired by Hoppus' residence in San Diego, before the move to Los Angeles. "I lived in a part of San Diego that's one of the most beautiful places in the country, but it's also one of the most evil sickening places," said Hoppus. "People are just ugly to one another." The title was inspired by a woman who started a strict homeowners association in the city. "Cliffdiving" was inspired by Hoppus' teenage summers growing up, where he would embark upon his friend's house and dive into the pool from the rooftop. The track is therefore about "embracing the unknown," further incorporating influence from the breakup of Blink-182 and the beginnings of +44. "Interlude" is most representative of the earliest work Hoppus and Barker put together. It was placed as a musical break to separate the upbeat pop punk track "Cliffdiving" and the record's "darkest" song, "Weatherman". That track is another early composition that was written directly following the breakup of Blink-182. "I was driving to Travis' house and the whole Blink thing had just gone down […] We had been talking about making a really dark, dirty song." The song was launched from the line "Just let me slip away, I'm barely holding on," and the music was intended to reflect that theme.
