Show HN: GreatDJ – Create and save playlists that sync across devices

Hi everyone, Wanted to show you a small side project I've been working on - GreatDJ, where you can create and save Youtube playlists and optionally have them sync across clients/devices. They main use case was to allow everyone at a party to push songs into a common playlist (say, a computer that's connected to the main speakers).

Lately I've been working on making that easier: if you have a computer on 'party mode' and use a phone on the same network to access the site, you'll be automagically redirected to the same playlist so you can start pushing songs straight away!

The whole thing is also open source: https://github.com/ruiramos/greatdj

Have fun, feedback would be amazing, thanks!
