I absolutely cannot stand music and noises that play on a site — especially if they play in a loop. Given my penchant for keeping a high number of browser windows open on my computer, sometimes I can't figure out where the noise is coming from. In fact, that's exactly what just happened to me . . . the Droid noises on the Verizon Wireless site confused me for a solid five minutes.
What about you? Do you detest the background noise as much as I do, or are you a fan?
