In general most songs are not communicating the right message. We are wasting a mass communication channel. Imagine if we could have a platform that could help artist co-create songs with its users or fans. Similar to the ideas behind crowd sourcing but with the artist being the mastermind behind the creation.
It will need to be a platform similar to a kickstarter but for artistic creation where the users will have to release all rights to the artist that is managing the process. I imagine having different groups of users trying to push certain messages through music.
In 2012 the global music market represented US$16B in retail sales.
