Why do I wake up at certain songs?

well now that you know you wake up to the song your letting your brain think that you want to wake up at that song, and so i think your gonna keep doing it. make a differnet playlist or erase the song. your brain knows that thats its cue to wake up. so you need to train it otherwise. for example next time you sleep put that song like number 4 on your playlist so your deeper into your sleep and then try and make your brain realize that it can go to sleep with that song
