Someone who finds a song they really like and then listen to that same song for a long period of time.
Person 1: rachie is a song snatcher.
Person 2: I know right she only listens to EARFQUAKE.
This occurs when you're singing a song and someone near you jumps in and starts singing right along with you.
A: "I ain't sayin' she a gold digger"
B: ( song snatcher jumps in enthusiastically) but she ain't messin' wit' no broke..."
