Movie about a killer who plays a specific song

Hi, I’ve been searching for this movie for literally years now. There was a girl and she was at a bar/pub/cafe. A woman called the bar and asked for the girl. The woman made the girl listen to a song and said that “if you ever hear this song somewhere, run”. And the girl later hears the same song coming from a truck on the road outside the bar. That’s all I remember. Help me please 🥺
