omg i have this issue reallly bad. i ALWAYS wake up with a song playing in my head. just some random song, sometimes ones that i havent heard in a long time. it seems uncontrollable and it drives me nuts. it is soooo annoying. i find listening to other music kind of helps but then i get those songs stuck in my head. it is so maddening. i dont have any advice but just wanted to say this happens to me too
