I sometimes hear comedians such as Bo Burnham and George Carlin (favorite by the way).
On YouTube, I listen to 80s Japanese music. I really enjoy it. How I discovered it, let me just say that it was just in my recommendations for some reason. I also type some songs/music videos that I know, and Game Grumps. I listen to some bands/singers. I didn't list them so that my reply wouldn't be so long because I really would go in depth and type paragraphs. If you want me to tell you some recommendations, feel free to ask.
Yeah, music can get kind of tiring. What helps me is to listen to different stuff, sing it, or just taking a nap/break (or something).
Speed paints on YouTube are better than art tutorials: (1) you can hear new music, (2) some actually give you advice, and (3) the person drawing can talk about stuff. Yeah, the art tutorials aren't so great. I think it's better to talk to someone who is an artist as well, but I'm not sure because I never tried that. I don't have any artist friends.
