Very fine line up. I'll say Katy even though i love LOUD's #1 singles, and rude boy >>> 99% of the songs out there. but Katy's singles are top quality in terms of sales, radio success and video views
Even though I did like Rude Boy and LOUD's #1s, I find them a little forgettable. ET, Last Friday Night, and Firework still sound fresh every time i listen to them, so Katy.
