Showing BPM, KEY in File browser on Prime 4 OR auto create playlists from folders

If I was to manage this today

  1. I will use engine dj (desktop) directly with external drive.

  2. I will have one Parent folder containing all the subfolders you mentioned

  3. I will drag this Parent folder to Engine DJ collection. Engine DJ automatically will create all the subfolders in the playlist tree.

  4. Engine DJ will analyse and do it’s thing

  5. If i add new tracks to some subfolders, I will delete the main folder in Engine Playlist tree and drag the Main folder again.

  6. Step 5 does not remove tracks just the playlist
