I probably do 90 percent styles because I like the freedom to be in control of the song structure- open up solos, end the song when I feel it’s time.... Sometimes I run into a song that I feel a style does not do justice to.... Usually because of very specific drum, bass parts or very specific breaks, meter or tiempo . changes. In those cases I can usually find a good midi file or audio track. But to be honest, I would probably use styles a lot less if I had better piano skills , especially left hand bass or bass pedals. Maybe in my next life !
