The RIAA has nailed one of the most prolific file-traders in the U.S., filing a lawsuit against 12-year-old Brianna LaHara.

When not at the playground with her friends, "Biggie Brianna" is trading music files from her home in New York. The little girl received one of the 261 lawsuits filed by the RIAA (Recording Industry Association of America) on Monday, according to the New York Post. She may look like a sweet and innocent child, but the RIAA says it's only going after major copyright violators at the moment. So you make the call.

"I got really scared. My stomach is all turning," Brianna told the Post. "I thought it was OK to download music because my mom paid a service fee for it. Out of all people, why did they pick me?"

It turns out that Brianna's mum paid a $29.99 service charge to KaZaA for the company's music service. Brianna, however, thought this meant she could download songs at will. How naive!

When reporters charged into Brianna's home, she was helping her brother with some homework. She is an honors student at St. Gregory the Great school.

Brianna could face charges of up to $150,000 per infringed song. but we have a feeling this might be a tad unrealistic. We suggest the RIAA take all of her toys instead.

"Nobody likes playing the heavy and having to resort to litigation," RIAA president Cary Sherman said in a statement. "But when your product is being regularly stolen, there comes a time when you have to take appropriate action."

Go get her, Cary.
