Bill, your examples above clearly go to show that ALL music consist of repetitive styles, therefore, each of those YouTube examples sound quite similar because they ARE repetitive, especially with the drums, bass and other voices. The only thing that separates one from the other is the lead voices, which are improvisational at best. Sorry Bill, but I really see no difference based upon your exemplars. You could do the exact, same thing with any arranger keyboard right out of the box and probably do it better because of the many automated features at your fingertips.

All the best,

Gary
