Hey guys,

On a worldwide scale, and in 2012, who are the top / most successful / most famous 10 artists in your opinion? This includes relevance, fandom, album sales, concert / ticket sales, endorsments, online presence, international fame...

For women, I think the top 10 for the last few years and as of now are Adele, Rihanna, Katy Perry, Madonna, Britney Spears, P!nk, Beyonce, Lady Gaga, Shakira and Nicki Minaj

For men, the top 10 in my opinion (including groups): Maroon 5, Linkin Park, Coldplay, U2, Pitbull, Eminem, Jay-Z, Kanye West, Justin Bieber and One Direction

Didn't include Fergie (no huge for the last couple years), Jennifer Lopez (good single sales and other ventures but abysmal album sales), Taylor Swift (country stars' popularity outisde North America is debatable), Bruno Mars (too new to be considered a worldwide superstar) and will.i.am (flopping hard in the US for all single material although having success elsewhere)

Do you agree? Do you disagree? Who are your top 10 in your opinion in each category?
