Of all the senses, smell is the sense that is the most closely associated with memory. Some smells can transport you through time almost instantaneously. A whiff of a long-forgotten perfume and you can almost taste your first kiss. And while the sense most closely associated with smell is taste, not too far below those senses is sound. If there's one thing that can take you back in time, take you back to those feelings, to that moment...it's the music. There are a lot of firsts in your life - but I bet one you'll never forget is that first song you cranked after you got your driver's license.
