The Dave Matthews Band is the fourth biggest-grossing act of 2010, with $23.9 million, and Justin Bieber is fifth with $22.4 million.
The top 10 is rounded out by Taylor Swift ($20.7 million), Michael Buble ($19.8 million), the Eagles ($18.3 million), the Black Eyed Peas ($16.8 million), and Sir Paul McCartney ($14.1 million).
A Billboard spokesman says, "Lady Gaga was inescapable in 2010. The pop singer, only a few years removed from her original hair colour and shows at small downtown New York venues, so thoroughly dominated the last year that it seemed almost a foregone conclusion that she would top the Money Makers list."
