My favorite kinds of music is the kind that surprises you. While I enjoy conventional type songs (verse, chorus, verse chorus, bridge, chorus), I prefer songs that take you on an adventure. This includes jam songs (Grateful Dead), and songs with many detours and lots of dynamics (Rickie Lee Jones, Dave Matthews). Although most of my songs tend to fall into some kind of normal verse/chorus formula, I do tend to try and mix things up a bit. Which is why most of my songs last longer than 4 or 5 minutes.
