Oh. Music I know can play repetitively in my mind, which is annoying at sleep time, so I tend to listen to slow music I am not familiar with at bed time. Suno did generate good such music just now for me, even though it failed miserably to generate music for genres I like during daytime. Fascinating.
I have the same thing, really annoying. I can wake up at night at the same song too. I stopped listening music hours before bedtime, but that doesn't always help and I also tend to forget. I'll try out suno for this purpose. What do you use for prompting, if you want to share?
