Deprogram, Safety Third, various HowStuffWorks series, Nosleep and Creepypastas, and also I have NewPipe so I mainly just listen to long YouTube videos as podcasts. Disaster Breakdown, Plainly Difficult, RMTransit, and Mentour Pilot are my current educational channels. Barely Sociable, Nexpo, Rob Gavagan for horror and true crime stuff. Some channels interleave the video and audio a lot more so they're not as suitable for listening to.
