Hi Eric, the songs that I like to shop with are; AL Stewarts year of the cat, that song alone will give you all the instruments in one song. Vocals, piano, violins, sax, bass, guitars,etc, and the song carries itself along in a smooth yet powerful rythm and great timing and blending of instruments. Next up is Mike Oldfields dreaming in the wind. This song is so powerful that it will tax all but the best. This whole cd/ vinyl is absolutely stunning. In a rare oldfield, he has a singer with an incredibley powerful voice. Next is Molly Jonsons Messing around. Great smoky vocals with a quick pace. Great for testing the speed of drivers. Imho. One more is Ray LamontAgnes Be here now. Use this one for judging a black background from the speakers. Turn this one up a little bit so that the quiet passages are evident. These are the ones I use at the audio shows. Don't let the guys who are selling the equipment get to pick the music. They already know which songs will mask the speaker or equipments weaknesses. Thanks for the opportunity to give my feedback. Hopefully others will offer their songs. I'm always in the market for other songs to add to my list as well. Cheers
