umm, incase you didn't know. the more dynamic content you have on your site, and more listings you will get on search engines. THIS IS A GOOD THING! someone searching for a song that was playing, for example, last week on your station, might endup there and decide to listen to your station, being as it had played atleast one song that they liked.
anyway, search engines are your friend. if you really don't want to be on them, then don't make your site public.
