Simple Sleep Timer - App Of The Day 

Are you the kind of person who puts on the earphones and listen to music and then slips into sleep without turning off the music player. Well I am one of those people. Leaving the earphones with music on not only produces noise on your ears but also drains your battery too.
Luckily, Simple Sleep Timer by XDA Senior Member crazyfool_1 can lower your music volume, or even shut down your music player app, after a predefined amount of time.

Its incredibly simple and does the job. It will give you a maximum of 60 minutes to set the sleeping time.It could have been a little higher, my sleeping time varies from 20 minutes to 2 hours. So it would have been nice if would be a able to set time greater than 60minutes.

It also has a neat feature to lower the volume down after prescribed time without closing it.The app is in its early stages of development. So might possess bugs. Overall it is a simple and handy app to have. So give it a try...
