I've never been good with figuring out the 'meanings' behind songs/movies/books, etc.  I tend to listen to music to be entertained.  With that in mind, bear with me if the song I bring up actually has some sort of horrible hidden connotation.  It's not intentional, I swear.  The song would be Lateralus, by Tool.  It starts out as a fairly mellow song, with a long, vocal-free intro.  This mimics my first week here, where everything was fairly simple and i was just learning the ropes.  Oh, and there were only 8 people here.  When the vocals come in, they're deliberately syncopated, and slowly rise in intensity, representing the buildup as people return and I start learning more and more.  Of course, it's also just a great song to listen to when you're doing work.
