I agree...they are the virtuosos of the auto-accompaniment world...they mostly use software to create the styles, but, you have to have the ear and musical sense to make them sound convincing. A real art.

And yes, it is their music, but they are good guys to have in my virtual band, when my other mates are not available for practice or play.

I like using styles, because I can change the feel of the music more spontaneously....and it's fun; at least for me.
