I listen to different things when falling asleep for about 20 years now; podcasts lately, but also mp3s of movies and tv shows (mostly comedy shows) that I saw many times already. I pass out almost immediately when the sound starts, I have nice (lucid) dreams and if I wake up too early it is only because the sound stopped for some reason; switching it on knocks me out again. When I have nothing on, I have trouble sleeping and when I wake up, I might just as well get up. For me it really works, but I know many people find it weird. Comedy tv shows work best for; best dreams and most relax wakeup time, but podcasts about easy stuff with not too crazy sounding hosts works well too.
