hm, i really don't know what song to pick for this because i don't really know a song that makes me fall asleep? that's actually kinda weird. haha! but, i guess i'd have to pick something slow - maybe like celine dion?! or perhaps a jewel song?
but, i guess for sake of answering this one - i'll pick
although - when the hook is in eminem's song 'stan' - it doesn't make me sleepy AT ALL! but, her solo song does sort of make me a little sleepy. it has the rain in the background and her soothing voice ... zzzz ;]
