Cover art for A Self Called Nowhere lyrics by They Might Be Giants

Um, it's definitely "a thing named id" not "it" and by "id" (one syllable, say it like "it" but with a "D") they are obviously referring to what we would think of as the subconscious mind. If you didn't already know what id is, I question the legitimacy of your TMBG fan status...most of us are pretty informed on things like that. ;)

Also, there should be another line after "where they tore down the garage". It should be "to make room for the torn down garage".

No idea what this song's about, but I get the feeling like a lot of other TMBG songs, it's about the innner workings of the mind.
