I listen to a lot of music. Azealia Banks is one of the many artists I've been hearing on my iPod of late. One song, Luxury, off of her mixtape Aquababe...no Fantasea is really hooky. I love it. Weird, strong melody, but the total gist of Don't Stop the Music by Rihanna. Very similar, but personally I think that Banks's melody is much more interesting than Rihanna's.
P.S. : Whistling in Azealia's song sounds like Crystal Waters's Gypsy Woman.
