It was somebody collecting electronic music that vibed well with playing rogue and nethack. I just remember it had a bunch of great links and also mentioned "Chill beats to identify items to"
Cannot find it on here for the life of me, must've been last fall.
I spent about an hour yesterday looking for a post that was within the last month. I eventually gave up looking back in the timeline once I remembered one of the people that reposted it.
I know bookmarks exist, but it'd be neat to be able to save posts with some kind of "notes" or "tags" field inside of cohost itself so that I could search it when i'm looking for stuff like this in the future.
