My mistake - sorry, I didn't explain good enough. So I try again :-)
Sometimes I do want to playalong with a style that is completely random. But since there is no option yet to let the software pick a style randomly, I have to open the style picker, scroll down manually and stop somewhere for picking a style. But what a person finally picks this way is not really random. It's influenced by selective perception, scrolling habits, unconscious laziness and so on. Therefore I'd find it nice if the option would exist that BiaB can pick a style ramdomly.
