That a bunch of teenagers stop talking and just start listening? I am a teacher and always play a song during warmup...usually a rock song or one I've let the students pick (with me screening it first). Today I played "All For You" by Julio Iglesias and Diana Ross. I wanted to see how the students would react. I heard a few "who is this singing" and the room just began to quiet down...and nobody scoffed at the song.
