Beyonce's status can't be compared ...I am agree with everyone here..who are favouring beyonce.. Destiny Child was also a big hit.. Even Britney should have more songs in this list But I think this list lack Eminem's songs c'mon everyone knows that eminem has a great number of hits this decade & I know everyone agree with me..he is considered as artist of decade One thing for sure that..there is very mix variety of rock artists in this list.. I think Only Green day has 2 songs in this list ..otherwise other rock legends has only 1..! Bit disappointed that they didn't include Muse! And all Lady Gaga Haters...hello U should all check ..Poker face deserve to be in top 3 ..it was one of the best single of this decade Carrie Underwood..no surprise that she has more than 1 single Umbrella should deserve a spot in top 10 ..! Otherwise this whole list is good!!xo
