Good going.
I need to go explore that everynoise page further. I was mistrustful at first because I'd used the parent site before and found it cool but inaccurate with some less-popular genres.
Here's a music finding site I've had some success with: http://www.gnoosic.com/
JQBX is a newish platform for community DJing. Basically a chat room with music the users control by taking turns on the DJ booth. The link should have taken you to the web app (there also stand-alone apps for mac/windows/mobile) -- which would likely be empty since it was the middle of the night over here.
When in the room, click on 'Be a DJ" and fill your queue with songs. JQBX adds two playlists automatically to your Spotify: JQBX Queue and JQBX Starred. You populate the Queue playlist with what you want to spin, hit sync in the app and you're ready. I'm usually in it (this room or others I like) during work hours (EST).
Here's a FAQ from JQBX themselves: https://www.jqbx.fm/faq
