It's not hills and valleys, but more like a series of potholes.  The
infidelity would come from their source material (for example, they
might take a cassette recording and make a CD master with it).  The
CD media cost in any volume is around 90 cents each, so with no
royalties, no performance fees, it would be pretty lucrative!
