This is Beyonce's song Irreplaceable, which is great to use for teaching MUST for Logical Conclusions. After you listen to the song you can do the last exercise where students have to imagine what must have happened before. You can sketch a picture (stick figures) on the board- of a house, a woman, a guy, some packed bags and a cab waiting. Tell the students to imagine they are the neighbors and they try to figure out what must have happened that the woman is kicking him out of the house. It's fun and the students love it!
