After her child used Kazaa for a school project, Michele Scimeca of New Jersey received a letter from the RIAA.

So she sued Sony, Universal and Motown, claiming the demands that she pay up to $150,000 per incident violates RICO statutes.

Scimeca's attorney says "They're banding together to extort money, telling people they're guilty and they will have to pay big bucks to defend their cases if they don't pony up now. It is fundamentally not fair."
