Show Off
The crowd picks the songs. You see them on stage. Instantly.
The audience browses your catalog on their phone. They pick a song, add a key change, hit submit. You see it on the stage HUD before they sit down. Show Off handles the queue, deduplicates requests, and fires OSC triggers to your lighting rig when you approve a song. Built for River Idol. Works for any live act.
