Possibly the best known song by They Might Be Giants, and for good reason. "Birdhouse in Your Soul" comes in at #1 on this ranking for the marriage of its metaphorical, yet also starkly literal lyrics with its complex, and yet also dreamily simple music. The song's story could arguably be about a nightlight, or from the prospective of some larger protector, and though some lines are clearer than others, there is a message: someone is looking out for you, and you should welcome that into your heart. "Birdhouse in Your Soul" hits a perfect balance between the classic alternative rock sound, heavy on guitar and keyboards, the New Wave sound of TMBG's earlier work, and the horn-and-electronic pop that increasingly populates their later compositions. The lyrics, even at their most nonsensical, are rhythmically comforting, easy to remember, and full of interesting syllables and references. "Birdhouse in Your Soul" is a song that crosses a number of different musical boundaries, and deserves the reputation it holds amongst fans of the band.
