I just went to technical death metal and free jazz. It is a really nice selection of music subgenres.

(I did post a link on fb, but not the official reference. :-)

Point is, depending on their music selection size, I'll have a window open a long time (I'm not an expert on the internet radio stuff, but this seems good). Go use anononymous (edit: I meant -- in the web browser) if you really don't want to risk fb interaction.
