Seattle Sound the Same

To quote Jane's Addiction: nothing shocking. Fans voted to name the new MLS franchise in Seattle after the USL.1 club. According to the press release, over 14,500 fans voted and half of them submitted write-in votes -- "49% of which included a derivative of the name Sounders." But what is derivative of the name Sounders? Sound? Noise? A long surgical probe FC? Maybe HotForWords could explain. Along with their uninteresting, uninventive name, they unveiled their colors and crest (oh, green and blue in Seattle...how original).
