She's made hardly any money. Being that she's $4,000 short to start off with, you have to remember that she's only the singer. She neither wrote, produced, distributed or anything else to do with that record.
And it's only been distributed on the internet so far, where royalties are notoriously low. Once the record company, songwriter, producer and everyone else has had their cut, she'll be sitting on a few grand if she's lucky.
There's scope for her to make real money once she gets on the media train I suppose with interviews, magazine articles and the such like. Or if she goes on tour maybe. But from that video - it's more agro than it's worth in my opinion.
