Hey @rok-sivante. Since I became involved with @utopian-io about a month ago I have felt that there could be a similar model put in place for music. Here are some of my initial thoughts:
A utopian-like music program, let's call it "Stems" for now.
Qualified Musicians can create projects in which they can request specific musical bits and pieces from the Stems community, such as a samba rhythm in 119BPM 85 bars in length, vocal part using this text and this melody, an acoustic guitar part in the style of "Choice" these chords 102BPM.... you get the idea.
Stems community musicians could then submit their contributions based on what is requested by the project owner.
Project owner could then 'approve' the parts he or she would like to use. These parts are then upvoted by the @stems account at a relatively high rate.
All other contributions are reviewed by stems-mods and if they are deemed 'acceptable' based on specific rubrics then they too are upvoted by the @stems account, but at a lower rate. These contributions are then available for any future musician to use as part of new pieces of music. When contributions are made the tags used will aid in the searching. For example, stems, instrument, tempo, key, style Musicians looking for a specific stem can search for what they need.
These are just some ideas bouncing around in my head. But I would be VERY interested in organizing something like this to roll out to our community. I have been involved in dozens of collaborations here on Steemit and I know the power of community in the music-making process.
Lots on possibilities. Let me know if you want to chat further about this?
Cheers,
