"Idea Pop!"

I had to entitle this post like that for my brother, who always says "idea pop" if he has an idea. But this time, it's me having an idea.

I don't know who else has this problem, but I have a major issue with forgetting to turn off my music player before I fall asleep. Naturally, I can't tell which moment I will fall asleep in, so either I'm still awake without my music playing or asleep with it still on. This turns out to be problematic most mornings when it comes to waking up without any battery left since that means that I can't wake up listening to an upbeat song.

So, my major idea for the moment is a music player with sensors in it. Sensors that can tell when you're starting to fall asleep. It will quiet, gradually turning off, from the moment you start drifting off to the moment that you end R.E.M. sleep. It will turn all the way off after the exact moment that R.E.M. stops, turning on- quietly at first, building up to higher noise- when and if it senses that you're waking up for a midnight snack or for the morning.

Anyone like or dislike this idea? Or is anyone an inventor that could make this happen? (Just kidding there. I mean, unless you really want to...) I'd like to know what you guys think in the comments below. Thanks!
