I also used to do that (and it helped) but I couldn't figure out the best way to listen to music in bed; trying to fall asleep. Using headphones got annoying since I can't move my head around and earplugs did hurt after a while. Sometimes, I also woke up entangled in them, lol So I kind of stopped doing that, too. And listening to music from a speaker isn't always possible (annoying for others) and it's also not the same.

I use the phone, put it close but not too close where I can still hear it, and set the automatic closing time 👀

The fear was that I didn't know what to do with all that time awake. So I was afraid of being too bored to much.

oh, I don't think I will ever get bored, that's always fun thing to do and try.
