I do not know about Spicier or Jazzier, but one thing that I would do with this song is use fingerpicking styles. find the melody line and get your fngers movin'....It makes the song very much busier, and if you could keep up with the normal tempo, it is a very good excersize. This is a hard tune to play by-ones-self and keep it interesting, but I would suggest fingerpickin this one if that is the case.
