I work at a record store and selling stereo equipment is something I do almost every day. Two of my favorite songs to test things out for people are "Money for Nothing" by Dire Straits and "Refugee" by Tom Petty. It never fails and within the first twenty seconds or so they are sold, gets em every time!
