That thought. Today everything that is social develops. And all that “non-social” is “socialized”. There are social music services, but they all have the same principle - people listen to music and share their opinions with others. Thus, the rating is built up - and you can always be aware that the most listened / downloaded / sold is now.
But my idea is different. What if you make a social service to create music. For example, I am a good poet and came up with very good words for a song, but the composer of me, like the singer, is absolutely “none”. And what to do? And that's what. I post the words on this service. In addition to me, the same words are laid out by other users. The majority of users vote. In the end, the leader is determined. Further. The man feels like a composer. He writes music to words and adds to her words. It can be synthesized on your home synthesizer (in its program, etc.) so that users can listen and estimate how the melody sounds. Again - vote. Leading music is determined. Further. There are words. There is music. It is necessary to revive all this. Someone has a guitar at home, someone has a drum, someone has a super program for creating music, someone has a piano / violin / double bass / trumpet, etc. The collection of parties for our music begins. Someone feels like a good sound engineer and merges all parts into one. Further. Someone feels like a singer. Writes, lays out. And so different people. Users vote, discuss, offer to change something. As a result, a good song appears - a social song - one that a priori likes a lot of people. If you think globally, then in the future, when the service develops, producers will start looking into it. And you get such a social factory of stars :). Although, people will start to drive producers out of there, because the service will turn from social service into something incomprehensible, where everyone will shine with his talents not for the sake of a common cause, but for the fact that someone will notice him suddenly.
I do not know, maybe this is somewhere already there ...
