I didn't get that impression at all. Sure she got herself into that mess, but because she assumed her 'game' would be an easy win, so she gets some supplies and some fun for free. Things obviously didn't go as planned, she starts struggling, and gets punished for it. The only places music comes into play is at the end of the sex, when it has gotten a bit rapey, and when she's trying to collect herself after killing him. Neither bits felt like they were trying to make me feel sad or sorry for her. All in all, it feels very real. She made a mistake, and it had big consequences. She won, but at what cost, and et cetera.
