Does anyone know any songs that I can listen to, to go to sleep?

I need some new songs to listen to and lately im into the slower songs. and i would like some songs that are slowish so that i can fall asleep to. i dont want any instrumentals, they can be from any time period except like jazz stuff. i like country so if you can think of any country songs. i like songs like boston by augustana and beautiful by christina agueliara, and the slower john mayer songs. so i would like the help.
