Music is blanket transmitted (for example, via satellite downlink transmission)
to each customer's computer-based user station. Customers preselect from a list
of available music in advance using an interactive screen selector, and pay only
for music that they choose to have recorded for unlimited playback, for example,
by a "CD burner". An "ID tag" is woven into the recorded music so that any illegal
copies therefrom may be traced to the purchase transaction.
