This song brings up an interesting idea about the way that love and relationships might work... like the way software development works. It is not a one and done thing; it changes and (hopefully) improves. Sometimes you have to look at relationships (with people in general and specific individuals) like you might approach testing out software. If there are bugs in it, you do what you can to fix them, update, and move on to the next version. See: http://en.wikipedia.org/wiki/Software_release_life_cycle.
