How Juke4ME works

In short: Juke4ME turns the sound system of a bar, restaurant or café into a collaborative jukebox. Guests scan the QR code at their table, search YouTube Music and vote on the queue. The venue runs a player in a browser on a small device connected to its amplifier, so nothing has to be installed on the guests' phones and no guest account is ever created.

What happens when a guest scans the QR code?

The QR code is a plain link to the venue's page on app.juke4.me. Scanning it opens a progressive web app in the phone browser: the venue is already selected, the queue and the track currently playing are on screen. There is no download, no sign-up and no password. The same QR code stays valid for the life of the venue, so it can be printed on a table tent, a coaster or a sticker at the bar.

How does the queue decide which song plays next?

Every track added by a guest enters the venue queue with a vote count. Guests vote for the tracks they want to hear; the queue is continuously re-ordered by votes, so a track that several people support moves towards the top. When a song ends, the player plays the next track at the top of the queue and starts downloading nothing in advance: the catalogue is streamed from YouTube Music on demand. A guest who adds a track and nobody votes for it still sees it in the queue — it simply waits its turn behind the more popular ones.

What runs on the venue side?

Two things, both in a browser:

• The player — play.juke4.me — displays the current track, the cover art and the next tracks, and outputs the sound to your amplifier through the device's audio output. A mini PC, a spare laptop or a tablet connected to the sound system is enough; there is no jukebox cabinet and no proprietary box to buy.
• The dashboard — admin.juke4.me — is where you build playlists, schedule them by time slot, publish announcements and offers, read the statistics and manage several venues from one account.

Can the venue keep control of the music?

Yes, and this is the point most venues ask about. Your agenda always wins over guest requests: a playlist scheduled for happy hour or dinner plays as planned, and requests only fill the queue outside those slots. At any moment the venue can pause, skip a track, remove an entry or switch the jukebox to full automatic radio. The dashboard settings are per venue, so a group with three locations can run three different atmospheres from the same account.

What happens if the internet connection drops?

The player keeps playing what it has already loaded and keeps its position in the current track. When the connection returns, it reconnects on its own, resumes the track where the room actually is instead of restarting it, and the venue becomes visible again in the guests' app. Tracks already played are cached on the device, so a short outage does not interrupt the evening. The design rule is simple: a reconnect must never restart the song the room is listening to.

Do guests need an app or an account?

No. Guests never install anything and never create an account: the QR code opens the web app, they pick and vote, and that is the whole interaction. Because of that, Juke4ME asks for no personal data from guests, which keeps the venue's own privacy obligations simple. Guests can optionally keep their picks across visits with a one-tap profile, but it is never required to request a song.

Where does the music come from?

Juke4ME does not host or own a music catalogue. Tracks are sourced from YouTube Music through the official platform, which gives the queue access to a very large catalogue without the venue maintaining a local library. The venue remains responsible for the public performance licences required in its territory; in Malaysia the relevant bodies are MACP, PPM and RPM.
