There are a number of songs out there that have a sweet meaning from one perspective, but a really creepy inference from another perspective. One such song is Every breath you take by The Police. Although it is a very romantic song when you listen to it.
However, once you take into account that you don’t know whether the song is about the girlfriend or whether the girl knows that she is being watched you start to get the creeps. Try to watch the video with this perspective and you will get shivers down the spine how he watches every move of the girl without letting her know.
The creepiest popular song in my opinion has to be Every Breath You Take (I'll Be Watching You) by The Police. This song sounds sweet because it sounds like a man talking about how he loves his girlfriend but he never really says that the song is about his girlfriend or even that she knows that someone is watching her.
If you really listen to the lyrics it is really creep how the guy is watching every second of the day. Even if he was talking about his girlfriend it would be creepy.
