Granted, it is not a large-scale study, but I am surprised there isn't a "Snapchat of music" or more contemporary app gaining steam. I expected music would be one of the first categories to be redesigned for today's teens/digital natives. Spotify, Pandora, Rdio, Apple Music are all big incumbents now.
