That's simple to awnser. We've a few things in mind that we would like to add to the website, and esp to the main menue. But with html we had the menue on every single page. Which means that I would have had to change the menue on every single page (with the timeline and the lyrics we come close to 500, and because of the german version you have to double that), if we' like to change things. Now with php I only have to do it once. "Frames" suck, and trulla convinced me to use php.
