f(x)'s newly released mini album NU ABO is already topping the online charts. Especially the title track NU ABO which has been taking the #1 spot on numerous sites. On Dosirak's Top 100 chart, monkey3's daily chart and Bugs' Top 100 chart, NU ABO is currently at #1. Melon is the only site in which they haven't taken the top spot, and even there, the girls are firmly holding second place. On May 6th, f(x)'s music video will be released, so sit tight for that. On the 7th, they'll make their comeback on Music Bank and continue their streak of comebacks on Music Core and Inkigayo. Are you guys psyched?
