[Updated on April 25, 2007] Love 'em or hate 'em, there are songs that everyone knows. No matter where they are, people sing along to those songs, usually at the same decibel level as commercial jetliners. The next time you really want to annoy someone (your parents, your neighbors, the people sitting in the car next to you, etc.), get a big group of people together and try some of these classic lung-busters. No vocal talent required whatsoever.
