Ms Thomas said her legal team was looking at ways to get the fine reduced even more.
"Whether it's $2m or $54,000, I'm a mom with four kids and one income and we're not exactly rolling in that kind of dough right now," she said.
Shocking
The RIAA first took legal action against Ms Thomas in 2007. She was accused of pirating almost 2,000 tracks but the record companies sought damages for only 24 of them.
