I use .kar files, or midi files with lyrics embedded in both RB and PT, and it scrolls the lyrics and chords, and i find it to work very nice. Others prefer BiaB since it has the conductor feature and you can repeat a chorus or two with a click. I just do the songs as they are and it works great for me.
