Depends what you’re into
I like:
Air Safety Institute - https://www.youtube.com/@AirSafetyInstitute - they cover recent GA crashes, all sorts of stuff related to airplanes and what not. Really interesting and well presented.
HorrorGeek - https://www.youtube.com/@TheHorrorGeek - amusing reviews of horror movies
NerdExplains - https://www.youtube.com/@NerdExplains - really snarky and mean-spirited horror movie reviews
PeriscopeFilm - https://www.youtube.com/@PeriscopeFilm - Archival film footage from through the ages, just all kinds of crazy stuff
Ill Advised Records - https://www.youtube.com/@illadvisedrecords - relaxing music
Law & Crime Network - https://www.youtube.com/@LawAndCrime - Content about crime and trials and what have you
Cryochamber - https://www.youtube.com/@cryochamberlabel - Relaxing music
There’s a bunch more (the New Jersey museum guy, Drachnifel, bunch of true crime stuff) but that’s what leapt to mind first
very nice! should keep it safe for years to come.
