In regard to the recent letter by Wayne Sander of Bloomington, MN, I will say that in general, I totally agree. I have a link on my main page that goes to my listings. Music in good taste can create an atmosphere and set the mood for a buyer. Animation draws the eye, and that needs to be considered very carefully to be sure you are drawing the eye to something, not from something else. Multiple animations simply confuse.
Music is another matter.
I often access the web from a system with no sound card. As reviewers we particularly hate dealing with sound files. They eat up our time and our cache. A page that offers so much to read that I will be there for a significant time is a different matter, but it still should be the users option whether or not he wants to listen to your music. Perhaps he has his own favorite CD playing in the background.
