Sarah McLachlan may be best remembered for founding the all female summer festival tour Lilith Fair, but when I hear her song building a mystery, I always think of fall. Building a Mystery started to gain massive popularity and relentless radio play in the beginning of September when it debuted 1997. it’s video has a very shadowy, chilly feel to it as well, featuring lots of smokey mist and curtains blowing in breezes. The song also has the distinction of being the first song ever to be played by an iPod. Steve Jobs selected the track during a keynote address introducing the new technology on October 23, 2001.
