Very clever way of getting people to buy music on the iPhone. Hopefully it is not too late for that hipster thingy. The music proposed is by no means music anyone ever affiliated with any kind of serious hypster-business would speak about in public. Prove me wrong but this app proposes err … Katy Perry. Nevertheless the interactive parts are quite funny, the designed world is consistent and there should be way more animation in other apps. For now. I like.
