I built a "collaborative listening" app 25 years ago: https://youtu.be/IsXLEum7xBk Interesting to watch many attempts at this since then. BTW "Money For Nothing 24/7" definitely violates the DMCA, if you care.

Stack: LiveKit (WebRTC), Next.js, Node.js, Neon Postgres, AudD for music recognition.
What's new in 2.0:
Stream from browser tab or system audio (BlackHole/VB-Cable)
Music recognition with automatic deduplication and "winner selection"
24/7 demo rooms (NTS Radio, SomaFM, and yes... Money For Nothing on loop)
See Lobby rooms from inside a room
Push-to-talk overlay for hosts
Automatically add emotes dropping 7tv.app link in the emoji popup in the chat
Happy to answer any questions! PS. Audio can be shared only by desktop at the moment. Not mobile
I wanted to listen to music with friends who live far away. Not "watch a YouTube video together" - actually share what I'm hearing in real-time, like we're in the same room.
Pulse is what came out of that. Anyone can host a live audio stream from their browser tab or system audio. Listeners join, music recognition identifies tracks automatically, and there's chat with 7TV emotes. No account required - you get an anonymous code and you're in.
We're running demo rooms that stream NTS Radio and SomaFM 24/7 (indie project, not affiliated - we backlink to the original stations). There's also a "Money For Nothing 24/7" room if you want to loop that Dire Straits instrumental forever.
Think of it as co-listening infrastructure. Bedroom DJs, listening parties, or just sharing your current vibe.
