Listen, the reason they managed to do $80,000 per song is twofold:
1. The lady was an idiot; she was basically saying "lol I didnt dl anything" rather than "oh ****, sorry guys, I'll pay you my vacation money after I battle to get the fine down to size." The jury got massively pissed off after a long time of this and ****ed her over.
2. RIAA considers pirating music COPYRIGHT INFRINGEMENT. It's not stealing something physical/digital from the artist/record label. If it were that, her fine could only possibly be $18,000 at the very conceivable maximum. RIAA believes that when you pirate a song or whatever, you are robbing the record label of their digital rights, ideas, property, and copyrights. Copyright infringement is, using the dictionary definition, like you, without authorization, producing copies of Windows 7 and selling it of your own volition. RIAA observes how pirates will upload/distribute a digital (non-physical) item (since the item is not technically property , they can get away with saying it's copyright infringement because pirates DO in fact acquire a full copy of the music without payment or agreement) and then distribute it under conditions that are contrary to the record label's copyright. Notice how when you download ****, there's this damn agreement you have to click "I AGREE" on? That's mostly just copyright information. Basically, RIAA goes through these loopholes to absolutely DESTROY you for it - a maximum fine of $150,000 per infringed item, as according to United States Copyright Law.
