Reggae is a personal favorite of mine.  It's a type of music that many regard as a happy and soulful type of music.  Reggae music originated in Jamaica and was made popular by the legendary Bob Marley.  Reggae guitar is fairly simple, yet vital with it's role in the band.  The syncopated rhythm's and heavy reliance on the drums and bass make reggae music a genre to let your soul dance to.
