Drag songs into your playlist, name it, and save (1–10,000 tracks; 75 recommended for a full standard Singo board). Only processed songs appear here — upload a folder and pick each song's play window first. A new playlist stays in progress — visible only here — until you approve it; approved playlists appear on everyone's Playlists page.
Approved. On everyone's Playlists page and in the player.
Only here in the Builder. Approve a playlist when it is finished and it moves across.
