How do guests add their suggestions?
Dead simple. They scan a QR code (on the table, near the DJ, wherever), open a form in their browser, type a song name and artist, and hit send. Takes 30 seconds. No app, no login, no account. The suggestion shows up immediately on the DJs screen. Other guests can see the list too and vote +1 on songs they also want to hear. By the time dancing starts, the DJ has a live popularity chart.
