Let’s not forget that besides Styles,SMF's, MP3's, and Karaoke files., that we also have the option of playing full keyboard with no backing ( solo piano or vocal/piano) . Also we can mix it up more by playing LH bass ( or pedals) over a drum beat . Yes, so many options!

As for me, I mostly to do styles, because I like the flexibility of not being having to follow a prerecorded or sequenced arrangement. I use a SMF or audio backing track if I can’t find a style that suits the song or if I feel a style just can’t do the song justice. My wife who sings with me absolutely hates SMF, and any pre recorded/sequenced track, but. will give in if we feel like a style file doesn’t work.
