After several delays, Iggy Azalea finally decided to release “Wicked Lips” — an explosive EP that has the Australian rapper gifting us with a colorful anthem in “Lola,” a braggadocios club-hit in “Not Important,” a powerful track in “The Girls,” and a pool party jam in “Personal Problem.” To make a long story short, I believe “Wicked Lips” is an exhilarating body-of-work that you will have fun listening to.
