Although it lacks a standout single like "Birdhouse in Your Soul," Apollo 18 is a more consistent album than Flood, overflowing with ideas and pop hooks. The most noteworthy idea may have been "Fingertips," a "suite" of 21 song fragments designed to make each random play a new experience, but the meat of the album lies in pop songs like "I Palindrome I," "My Evil Twin," "She's Actual Size," and "Which Describes How You're Feeling." The album has a slightly darker feeling than its predecessors, but that just gives the album a resonance that was missing on Flood.
