Who knew headphones were such a great investment?!
Dr. Dre has topped Forbes' 2012 list of highest-paid musicians, thanks largely to his Beats headphone company. Britney Spears, Taylor Swift and Justin Bieber were also in the top 10, based on income they generated between May 2011 to May 2012.
Rihanna brought in an estimated $53 million, followed by Lady Gaga, who earned $52 million. Sure, that's not quite as much as Dre's $110 million, Britney's $58 million, Taylor's $57 million or the Biebs' $55 million, but it's still a pretty penny.
Diddy raked in an estimated $45 million, followed by Katy Perry with $45 million. Power couple Beyoncé ($40 million) and Jay-Z ($38 million) will surely be able to spoil Blue Ivy with their combined earnings.
