I am currently developing a couple of apps that will need some good music and reggae/caribbean may well fit the bill. I'm into cool grooves and a laid back style of music (as well as boppy/retro/relaxing) at they tend to fit my games perfectly.
I have just released an app called B'lox! on the AppStore, so I have a proven history (as well as the many apps I've developed for pc, GP2X and Wiz) over the years - just do a search for "Ian Price" and "B'lox!", "Dicey", "Balloonacy", "Off The Mortal Coil", "Guru Logic Champs", "Cat Trap", "Puzzled" to name just a few. All of these are freeware games.
