LOS ANGELES (Reuters) - You may be singing “Call Me Maybe” or dancing “Gangnam Style” to this year’s music, but it was veteran hip-hop artist Dr Dre who topped Forbes’ list of the 25 highest-paid musicians in 2012, released on Friday. California native Dre, 47, became one of the leading names in hip-hop and rap in the early 1990s and has worked with artists including Eminem and Snoop Dogg.
