Very close to five stars but... Nearly perfect  but when I try to play along and the music is scrolling too fast  I have to tap the screen to stop it; and that often causes a change in the speed setting  which is infuriating -- especially since it's quite hard to set an exact speed with the slider in the first place. Can we PLEASE have the music speed as a setting in the tune properties  rather than an onscreen slider -- or the option of one or the other? Many thanks.
