AudioGalaxy-like stuff

Is there anyone here familiar with Audiogalaxy's site? It's all in PHP, and there is something there which is really something... when you're searching for songs, there's an icon that when u click, it adds the song to the queue. But the page remains... the file is added to the queue without leaving your current page... and the icon changes color (this is easy with Js, but that's not the point).. Does anyone know how they did that? ____________________________ . Christian Dechery (lemming) . http://www.tanamesa.com.br . Gaita-L Owner / Web Developer
