This is the "MY CO-WRITER VOLUME 5: RADIO ROCK" cd-rom, and it features original backing track instruments to help you write original songs, and it's in good working order and LOTS of fun to use (the plastic cd case has a crack on the inside, but the cd itself is just fine). This cd was produced by the same company that produced the "Drums on Demand" drum loops series. This listing is for the "My Co-Writer" songwriter's cd only, of course. H515709.
