The Inevitable March of Recorded Music Towards Free

Mike Arrington:

The DRM walls are crumbling. Music CD sales continue to plummet rather alarmingly. Artists like Prince and Nine Inch Nails are flouting their labels and either giving music away or telling their fans to steal it. Another blow earlier this week: Radiohead, which is no longer controlled by their label, Capitol Records, put their new digital album on sale on the Internet for whatever price people want to pay for it.
The economics of recorded music are fairly simple. Marginal production costs are zero: Like software, it doesn’t cost anything to produce another digital copy that is just as good as the original as soon as the first copy exists, and anyone can create those copies. Unless effective legal (copyright), technical (DRM) or other artificial impediments to production can be created, simple economic theory dictates that the price of music, like its marginal cost, must also fall to zero. The evidence is unmistakable already. In April 2007 the benchmark price for a DRM-free song was $1.29. Today it is $0.89, a drop of 31% in just six months.
