Do you really think that's more likely than the defendant just stealing some music?
Actually someone coming up and getting on your wifi and downloading music is much more likely than you breaking into a major label's office and making a copy of the source files for the song, deleting them behind you.
Or perhaps you meant to say "More likely than the defendant just committing copyright infringement" Theft has a definition, it is not synonymous with copyright infringement.
As for your delivery, pull the stick out of your ass, being told you are wrong isn't the end of the world, welcome to the internet.
This is why we should not tolerate terms like "Theft" and "Pirate" being thrown around.
You are a victim of the industries use of words such as "Theft" and "Pirate" (War crimes on the high seas, yar!). You have associated the sharing of information with a crime. Which is what the copyright industries wanted, it pushes the debate in their favor and allows them to further push around grandmothers who never installed "Kazaa" as well as lobby politicians for protectionist laws that overextend what copyright and patents were originally for, "[t]o promote the Progress of Science and useful Arts".
