"Aquarius", while very trippy and weird, overall has a warm feel to it.
"Olson". It's like the soundtrack to peace of mind.
"In the Annexe." Something about that song gives the warm sense of security.
The ethereal, uplifting "Dayvan Cowboy." Most of the band's tracks, even the upbeat ones, have a sense of nostalgia to them, but "Dayvan Cowboy" is just straight-up joyful, without any strings attached. The music video is of a guy parachuting from the atmosphere with lots of footage of the sky above and planet below, as if to say "look at how awesome the Earth is!"
"Nothing is Real", despite it's title, is very sweet sounding and nostalgic.
