Bookmarked. I already occasionally listen to local and nonlocal police scanners via Broadcastify with my own playlists of atmosphere and ambient-shoegaze music. No joke. I'll use this. Some beautiful, fresh music on the roll here.
I loved your explanation: "It invokes a mood. It distills a spirit of night and cities that never sleep. Urgent events from a police scanner play upon a feeling of social connectedness. Combining that with ethereal music plays upon senses of tranquility, danger, peace, haunting, calms before storms, and life transpiring."
Would be nice if HN had a simple forum or messaging/alerts for these moments. My lists are a disastrous mess in Foobar. It's time to finally get up to par and organize what I can on Spotify or whatnot for these situations. Any way to message, or just check back in a few days?
