Stereo Tunes - Sell Project

Stereo Tunes — real-time “listen together” rooms with reactions & recapStereo Tunes is a production-ready “listen together” web app where people can join a room, queue YouTube tracks, and stay synced in real time. It’s built for small groups, communities, and remote hangouts — with a clean UX, a responsive UI, and a reliable real-time core (playback state, presence, chat, reactions).At its heart, Stereo Tunes solves the main pain of shared listening: everyone stays on the same moment of the same track. Users can chat, react, jump to highlighted moments, and open a room recap with the best tracks and best reactions — all without complicated onboarding.Core features1) Real-time synced playback (the “host-synced” experience)Shared playback state: current track, play/pause, seek position, server timestamp.Automatic re-sync via heartbeat with a tolerance threshold (prevents constant “micro-jumps”).Smooth handling of autoplay restrictions (first user interaction unlocks playback).Track end handling: when a track finishes, the system can move to the next track and keep everyone aligned.Why it’s valuable: the experience feels like one shared player, not “everyone pressing play separately”.2) Queue system (multi-user)Search YouTube and add tracks to the room queue.Play next / play a specific queue item.Remove items from the queue.Designed for group usage: members can contribute tracks, not just watch.Why it’s valuable: it feels like a real room where everyone participates, not a one-person playlist.3) Live chat — feels “alive” with system eventsChat supports both normal member messages and system messages:Member messages: standard real-time chat.System events: join/leave notifications, “playing track” events, reaction events, etc.Different message types can render with different styles (centered “islands” for system events).Why it’s valuable: rooms feel active and social even when people aren’t typing a lot.4) Emoji reactions + timeline momentsThis is the “killer” engagement feature:Users can react with emojis while listening.Reactions appear as animated bursts and are also saved as moments on a timeline.Timeline markers show the most relevant reaction buckets.Users can click a marker (or click anywhere on the custom timeline) to seek to that moment.Why it’s valuable: it creates “shared highlights” and makes sessions replayable and memorable.5) Room Recap (Best Tracks + Best Moments)After a session, users can open a Recap modal that summarizes the room:Overall totals: tracks played, messages sent, reactions, unique participants.Best tracks: top tracks ranked by reactions.Best moments per track: the strongest reaction buckets with top emojis.Top contributors: track adders, chatters, reactors.Why it’s valuable: recap turns a session into an “artifact” — something users want to revisit, share, and repeat.6) Presence (online members)Tracks who is currently online in the room.Heartbeat-based presence logic + leave handling.Useful both for UX (“who’s here?”) and for future expansion (roles, moderation, analytics).UX highlights / quality-of-lifeMobile-friendly layout and interactions.Clean UI with modern styling (Tailwind + motion animations).Designed to avoid wasted YouTube quota (limit results, cautious fetching).Handles tricky real-world cases (autoplay blocks, tab switching, partial YouTube availability).Use casesStereo Tunes fits multiple real-world scenarios:Friends listening together remotely: Share music while chatting — like a lightweight “Discord music night”, but focused.Community rooms / fan clubs: Public or private listening sessions with reactions and highlights.Streamers / creators: Run themed listening rooms where the audience reacts and creates moments. Recap becomes shareable content.Remote teams / coworking: Background music room with presence + lightweight chat.Events / small online parties: The queue makes it easy for everyone to contribute tracks.Why this is a strong acquisitionProduction-ready: Dockerized, deployable in minutes.Real-time architecture already solved: chat, playback sync, presence, subscriptions, cache patterns.Sticky engagement mechanics: reactions → moments → recap.Expandable: easy path to monetization and growth without rewriting core systems.Tech & architectureTurbo-repo: apps/web (Next.js), apps/server (NestJS GraphQL).GraphQL: queries/mutations + subscriptions.PostgreSQL + Prisma: durable data (chat, reactions, recap stats).Redis: fast state & ephemeral real-time coordination.Caddy: SSL + reverse proxy.Docker Compose: one-command deployment.Monetization potential (planned)Premium rooms (higher member limits, advanced recap, saved history).One-time purchases (recap export, customization packs).Donations (already supported via external link).
