Considering Steven Page's known mental illnesses, the Ed Robertson-penned song Crazy is a pretty heartwarming song about how everyone is somewhat unhinged mentally and it really doesn't matter.
"I'm crazy just like you"
"Light Up My Room" is a song practically made of "aww". When foam on a creek and a tire field that's on fire not only don't damper your spirits, but actually keep them up, you know what you're listening to is the epitome of heartwarming.
While the music video is mostly funny and clashes with the lyrics, "Odds Are" is mostly a heartwarming song encouraging you not to miss opportunities in front of you, just because you're scared of things which likely won't happen.
Heartwarming to the point that the lyrics explain that considering the odds, you have a better chance of falling in love by the time the song ends, than dying in a multitude of horrible ways.
