Solution & Features

No feature screenshots/GIFs yet — see Architecture for system diagrams. This page describes behavior; visuals are a planned follow-up.

Live, collective voting

Listeners vote on the next track's genre, mood, and energy from a running poll. Tallies update for every connected listener in near real time as votes come in — nobody needs to refresh to see the count change.

AI-generated tracks, on demand, per poll

There's no pre-rendered song library. Every track is generated fresh from the winning poll options by a music-generation model, turned into a finished, streamable audio file, and slotted into the rotation — all within the runtime of the previous song. See Technical Architecture for how, and Challenges & Solutions for why that's harder than it sounds.

Synchronized playback across every listener

Everyone hears the same song at the same position at the same time. A listener who joins mid-track is placed at the correct point in the song (not restarted from zero), and song transitions happen without a gap or reload — playback is treated as shared, global state, not a per-client audio player with its own independent timeline.

Real-time state, no polling

Tally updates, "now playing" changes, and vote-close events are pushed to the client over a live connection (Server-Sent Events) the moment they happen, rather than the client asking "anything new?" on an interval.

Resilient by design

Network drops happen. The client detects a lost connection and reconnects automatically with backoff, and a listener's session survives a brief disconnect without losing their place in the current song or missing that a vote closed.

Audio-reactive visuals

A waveform and a dot-matrix visualizer react live to the actual audio being played, driven by real-time frequency analysis of the stream rather than canned animation.

Secure by construction

Voting and session identity are authenticated end to end, and the backend services trust each other via short-lived, automatically issued credentials rather than a shared static API key.
