Forbes just released its list of the "World's Most Powerful Celebrities," a somewhat arbitrary compilation that ranks everyone from athletes to movie stars to radio personalities "based on entertainment-related earnings plus media visibility (exposure in print, television, radio and online)."
According to that formula, Jennifer Lopez is currently the most powerful celebrity, beating out folks like Oprah and Manny Pacquiao, to earn the top spot. Several musicians also made the cut, including Adele and Tiësto. But the 15 artists we've ranked after the cut have one thing in common: money.
From rappers to county stars, these are the 15 musicans who made the most money last year.
