Okay. I am just noodling on this idea. With the vast number of songs out there and the vast number of DJs around the world that are "connected" via laptops, it seems that we could do something that would be very interesting. The idea is that Serato DJ could provide a top x suggested next tracks based on crowd sourced data such as:
1. Playlists that DJs upload to the site
2. DJs opting in to share Playlists at the end of a set (currently we just close the application and not asked to submit a playlist - its a missed opportunity)
3. DJs opting in to share song selections in real-time
4. An algorithm that uses key, genre, artist, and BPM to make "next song" suggestions
5. Other?

The song selections could be based on our local library and/or Tidal. For me it would be interesting when I am practicing, working in an open format set, a festival or some other gathering where I want to be more creative in my song selection.
