"Why?" asked our intrepid reviewer. Dragon User don't pay up just for asking difficult questions. "Why" is not the point.
These are three entirely separate performances of Scott Joplin music (1) and Bach music (2) in four part harmony, played entirely on the Dragon. You cannot play games with them, write speedsheets with them, assemble with them, or indeed do anything except listen to them, but at £3.95 each they are cheaper than buying a whole new stereo player, and quicker than waiting for the respective pieces to come upon the radio is the point, so cut the philosophy, pal.
The public wants Scott Joplin played on a Dragon, the public gets Scott Joplin played on a Dragon. Don't blame us.
