Jqbx.fm is a lot like plug which as you know isn't really running anymore. This site works in a similar way except it runs through your Spotify premium if you have it. They have an app for apple and android as well as the website and if you have Spotify premium it's free. I am in no way affiliated with the site and it is open source without ads...just looking to invite people here to play songs like we used to do on plug years ago.
It essentially works exactly like Plug.dj where you have a queue of songs (that you can edit in spotify or the app) and join a room. Either listen or step up and dj. All dj's are on a one song rotation.
This is a link to the room I made feel free to post in this thread if you want to play some tunes.
