Rebecca Black has drawn plenty of scorn for her headache-inducing single "Friday," which took the internet by storm last week. (See the painfully catchy video below.) But as much as her detractors may hate to admit it, the media glare surrounding the 13-year-old singer has produced at least one notable benefit: It's making her some serious money.
