Please- No more Tin Pan Alley

I love Axpona.  I go every year and it's great to actually hear the equipment and meet the designers that you read about.  But the music selection is sometimes not the best.  I like a wide range of music.  I'm not adverse to hearing anything(well maybe not Rap). There are a lot of rooms to cover.  Most people want to listen for 5 or 10 minutes to get a feel for the sound of the system and possibly purchase one of the components.  Please, vendors play a few minutes of a variety of music so people can see how the system sounds with different music.  How's the bass, the vocals, the dynamics, etc?  They should play selections for no more than 2-3 minutes and move on.  I know it's more difficult with a turntable- but still.  Nothing more aggravating than going into a room and listening to a song you don't like for 15 minutes.  And PLEASE- no more Tin Pan Alley by Stevie Ray Vaughan. And I like SRV.  That song is WAY overplayed.  It is so well recorded it would sound good on a transistor radio. It tells the consumer nothing about the system.
