A little over 12MB, this applicaton opens up in a slick interface with metro type icobs highlighting various sections of the application.You can log in into the app through your facebook or goofle account or create a separate logon.However, apart from some minor customisation options for the front page, signing in has little to offer.The sections, which are divided into latest releases, top charts, editor’s picks and discover for various moods can be accessed by vertically scrolling the screen while the individual sections can be explored by swiping horizontally across the screen.i love this app so much.
