Music messaging apps are one of the most exciting and disruptive music consumer behaviours to emerge since file sharing first raised its head in the late 1990s. Apps like Musical.ly and Dubsmash have catalyzed entirely new ways for young music fans to engage with music, blurring the lines between creator and audience. In doing so they have ushered in the prospect of the            second song and continue to ask probing questions about just what music experiences should be. These apps represent a Digital Native feedback loop: built by Digital Natives for Digital Natives, a new generation of music tech to follow the last generation of services such as Spotify and SoundCloud that were built by Digital Immigrants.
