The theme song in the series "Monk" is "It's a jungle out there" by Randy Newman. You can listen to it here. When I listen to it, I always hear
People think I'm crazy, they worry all the time
But in the official lyrics it says:
People think I'm crazy, 'cause I worry all the time
No matter how often I try to hear the 'cause I, I just can't sound it out. When I try to sing along, I can't speak 'cause I' as fast as Newman does (if he really speaks/sings it, which I can't catch).
Do native speakers hear it? If they don't know the lyrics and listen to the song for the first time, would they be able to write it down correctly or is it just not there?
