The Number one: The Police, I'll be watching you. It’s still to this day perceived as a love song but the intent is really sinister and has major stalker vibes! Not what you want in a wedding song.
Number two: George Strait’s song lists a few crazy ex-girlfriends and explains his decision to reside in Tennessee, as a result, to stay away. It is never a good idea to mention ex’s of any kind, especially on your wedding day! Avoid this song and move it along.
