"Let It Flow" was written in the studio and originally featured an intro before the chorus section, which was later dropped. The song's original lyrics were scrapped, and re-written by Wheeler while the rest of the band were at a pub. "Innocent Smile" was written about "small town Ireland hoodlums", and is indebted to "Daydream Nation" (1988)-era Sonic Youth with its slow build-up. "Angel Interceptor" is a mix of punk rock and doo-wop. At the end, McMurray can be heard yelling "Whooo! Yeah, we’ve got it!", while he was on his first ecstasy trip. "Lost in You" was by influenced by the Beach Boys and written at the end of the recording process. Wheeler wrote "Darkside Lightside" from the perspective of someone who had sex with another person's girlfriend; it opened with Iron Maiden-like riffs and ended with guitar work reminiscent of Pink Floyd. The hidden track "Sick Party" consists of Hamilton and guitar tech Leif Bodnarchuk vomiting. It was planned initially to be part of an outtake on "The Scream", which according to Wheeler was "built up 48 tracks that started out like a murmur up to full on screaming". When it came time to mix the song, they were "too scared". Because the band felt "Sick Party" "turned out to be so funny", it became a standalone track.
