Lawler's Rule

[Sony]'s use of the software, which is designed to limit consumers to making no more than three copies of a CD, reflects an effort to alter a format that is two decades old and contains music that can be readily copied and digitally distributed.

It's an open-ended question whether the music industry will ever understand their consumers. Sony has begun producing CDs with more restrictions even as the electronics side of the company continues to introduce music hardware with mangled DRM schemes. They are actively pushing their target customers to both piracy and competitors (what is the iPod to Walkman sales ratio these days?). They need to offer a compelling platform, music at a reasonable price, and then upsell on extras.
