So it's no more "the worst BOC track ever" but "your least favorite BOC track"...
When listening individually, everybody has his favorite tunes (on "Geogaddi" I often press the repeat button for June & Candy) and "less favorite" (on "The Campfire Headphase", Farewell Fire is just like Zoetrope, too long and boring). But these albums are not only a collection of songs, every track is a part of the puzzle, a detail that HAS to be here.
If someone who never heard BOC before begins with one of those short tracks (less than 30 sec or 1 min), he may say "OK, that's nice, but short, not very elaborate, I see no magic here, it's sweet but even a 5 years old kid could do the same..." (and there are many vignettes on their discography, so he may not understand why it takes so long to release a new album). Objectively, many of their short tunes may have nothing special, but they are part of the magic, and music is not meant to be a question of objectivity. So back where I started: there CAN'T BE a worst BOC track, just a "less" (or least) favorite.
