Getting Organic Views - What's Working?

I have an old YT channel that I repurposed - it hosts 3- 4 minute videos of gospel music created by AI Suno.com - with subtitles and pleasant non-copyright vids. TBH I think the music is good if you like that sort of thing (but it's not everyone's taste, obvs). I started well - suddenly got a few 100 views from recommended videos, but traffic has really dropped off. I've been careful to use relevant tags and keywords in the description. What's working these days to get traffic to videos? I'm not looking to monetise just yet - just want to create a decent channel with regular views.
