Lofi Girl still has an active audience. >100k for each video. GameChops has a channel as well with >5k & <100k for each video.
The Musician's story adds to the vibe. If someone can relate to the creator, it helps to create more connection with the audience than a pure algorithm. The human curated/generated animations seem more coherent...even if it's on a loop.
I like some of the new AI animations for being novel...mostly futuristic. Though this will soon become common & something new will show up.
